Li, Sida;Hu, Chenyang;Cui, Xin;Zhang, Jiong;Liu, Liu Leo;Wu, Lipeng research published 《 Site-Fixed Hydroboration of Terminal and Internal Alkenes using BX₃/ⁱPr₂NEt》, the research content is summarized as follows. An unprecedented and general hydroboration of alkenes with BX₃ (X = Br, Cl) as the boration reagent in the presence of ⁱPr₂NEt is reported. The addition of ⁱPr₂NEt not only suppresses alkene polymerization and haloboration side reactions but also provides an H source for hydroboration. More importantly, the site-fixed installation of a boryl group at the original position of the internal double bond is readily achieved in contrast to conventional transition-metal-catalyzed hydroboration processes. Further application to the synthesis of 1,n-diborylalkanes (n = 3-10) is also demonstrated. Preliminary mechanistic studies reveal a major reaction pathway that involves radical species and operates through a frustrated Lewis pair type single-electron-transfer mechanism.

Electric Literature of 72824-04-5, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.

A nickel-catalyzed, chemodivergent 1,1-alkynylboration, and 1,1-dialkynylation of unactivated α-olefins was reported. This study not only provided an efficient and modular protocol for the divergent synthesis of propargylic boronic esters, their corresponding alcs., and gem-dialkynylalkanes I [R = TIPS, C(Me)₂OTBS, C(4-ClC₆H₄)₂OTBS, etc.; R¹ = OH, CCTIPS; R² = Me, n-hexyl, Ph(CH₂)₂, etc.] but also achieved a controllable, single or double cross-coupling of Ni/B bimetallic intermediates. Mechanistic studies revealed that diboron reagent (B₂pin₂) plays a significant role in dialkynylation reaction, serving as both the reductant and transient assisting group. Notably, both reactions showed high regioselectivities and good functional group tolerance. In addition, the synthetic value of products was demonstrated with several downstream transformations.

Landwehr, Eleanor M.;Baker, Meghan A.;Oguma, Takuya;Burdge, Hannah E.;Kawajiri, Takahiro;Shenvi, Ryan A. research published 《 Concise syntheses of GB22, GB13, and himgaline by cross-coupling and complete reduction》, the research content is summarized as follows. Neuroactive metabolites from the bark of Galbulimima belgraveana occur in variable distributions among trees and are not easily accessible through chem. synthesis because of elaborate bond networks and dense stereochem. Previous syntheses of complex congeners such as himgaline have relied on iterative, stepwise installation of multiple methine stereocenters. The authors decreased the synthetic burden of himgaline chem. space to nearly one-third of the prior best (7 to 9 vs. 19 to 31 steps) by cross-coupling high fraction aromatic building blocks (high Fsp2) followed by complete, stereoselective reduction to high fraction sp³ products (high Fsp3). This short entry into Galbulimima alkaloid space should facilitate extensive chem. exploration and biol. interrogation.

Li, Feng;Klok, Harm-Anton research published 《 Macromolecular engineering via polyhomologation》, the research content is summarized as follows. Polyhomologation of ylide monomers by organoboron initiators is a powerful and versatile C1 polymerization method that provides access to linear polyolefins (polymethylenes) that share structural and compositional similarity with polyethylene. Oxidative hydrolysis of polyolefins produced via organoborane-initiated polyhomologation affords hydroxyl chain end functional polymers, which enable further functionalization, and provide access to unprecedented polyolefin-based polymer architectures. This perspective briefly summarizes the important features of polyhomologation, highlights recent exciting developments and points out challenges and directions for future research.

Kitson, Russell R. A.;Moody, Christopher J. research published 《 Synthesis of novel geldanamycin derivatives》, the research content is summarized as follows. The toxicity associated with the geldanamycin (I) family of benzoquinone ansamycins when used as heat shock protein-90 inhibitor mol. therapeutics is ameliorated by substitution at the 19-position. The resulting 19-substituted derivatives have greater potential for success in oncol. clin. trials and for other medicinal purposes such as the treatment of neurodegenerative conditions. Having overcome hurdles associated with the sensitivity and complexity of these mols., through a variety of synthetic approaches, the synthesis of a series of 19-substituted geldanamycin derivatives is reported herein using optimized Stille and Suzuki coupling reactions. Further compounds were accessible via copper-mediated coupling and nucleophilic addition reactions. He new compounds are of significant medicinal interest, in view of their significantly reduced toxicity previously observed for this class of substrate compared to their 19-unsubstituted counterparts that have been evaluated in the clinic.

Kanazawa, Tomoaki;Nishikawa, Tsuyoshi;Ouchi, Makoto research published 《 Orthogonal C-B Bond Transformation as an Approach for Versatile Synthesis of End-Functionalized Polymers》, the research content is summarized as follows. Conventionally inaccessible end-functionalized vinyl polymers were synthesized via orthogonal side-chain replacement for terminal and repeating units of poly(alkenyl boronate)s. A terminal-defined polymer of isopropenyl boronic acid pinacol ester (IPBpin) was synthesized via RAFT polymerization, and subsequent cobalt (Co)-catalyzed end olefination afforded the polymer carrying the C(sp²)-B bond at the terminal and the C(sp³)-B bond in repeating units. Herein, the terminal C(sp²)-B bond was selectively transformable via palladium (Pd)-catalyzed Suzuki-Miyaura cross coupling, and subsequent transformation of the repeating C(sp³)-B unit gave the poly(α-Me vinyl alc.) [poly(MVA)] bearing various functional groups at the terminal. The boron-based stepwise polymer reaction thus overcame the synthetic difficulty of the end-functionalized poly(MVA), which is ascribed to the poor polymerization ability of the corresponding acetate monomer, i.e., isopropenyl acetate.

Jiang, Binyang;Shi, Shi-Liang research published 《 Pd-Catalyzed Cross-Coupling of Alkylzirconocenes and Aryl Chlorides》, the research content is summarized as follows. The first Pd-catalyzed aryl-alkyl cross-coupling of alkylzirconocenes and aryl halides was reported. A com. available N-heterocyclic carbene (IPr) as the ligand for palladium catalyst was critical to enable the challenging process. This mild protocol does not require base additives and tolerated a broad scope of both coupling partners bearing various functional groups and heterocycles. Moreover, both terminal and internal alkenes were applicable, and the latter underwent “chain walking”, giving the terminal coupling product exclusively. Preliminary mechanistic studies revealed a precatalyst activation pathway and inhibited β-H elimination due to steric bulk of NHC ligand.
