《Iron-catalysed enantioconvergent Suzuki-Miyaura cross-coupling to afford enantioenriched 1,1-diarylalkanes》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Tyrol, Chet C.; Yone, Nang S.; Gallin, Connor F.; Byers, Jeffery A.. Formula: C12H17BO2 The article mentions the following:

The first stereoconvergent Suzuki-Miyaura cross-coupling reaction was developed to afford enantioenriched 1,1-diarylalkanes I [R = Me, Et, i-Pr, etc.; R1 = Ph, 4-FC6H4, 1-naphthyl, etc.; R2 = Ph, 4-MeC6H4, 2-naphthyl, etc.]. An iron-based complex containing a chiral cyanobis(oxazoline) ligand framework was best to obtain enantioenriched 1,1-diarylalkanes from cross-coupling reactions between unactivated aryl boronic esters and benzylic chlorides. Enhanced yields were obtained when 1,3,5-trimethoxybenzene was used as an additive, which was hypothesized to extend the lifetime of the iron-based catalyst. Exceptional enantioselectivities were obtained with challenging ortho-substituted benzylic chlorides.4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Formula: C12H17BO2) was used in this study.

4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6) can be used to prepare sulfinamide derivatives by reacting with diethylaminosulfur trifluoride (DAST) and potassium phenyltrifluoroborate.Formula: C12H17BO2

And the article was published in Chemical Communications (Cambridge, United Kingdom) in 2019. Name: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane The author mentioned the following in the article:

A light-emitting mol. triad (BPCP-2CPC) with dual functionality was successfully synthesized and applied to solution-processed non-doped organic light-emitting diodes. The BPCP-2CPC triad contains 9-phenyl-9H-carbazole units as a host moiety tethered to a green-emitting core (BPCP) through a cyclohexane unit and exhibits thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) characteristics simultaneously. The BPCP-2CPC-based non-doped TADF-OLED devices showed a high external quantum efficiency (EQE) of 13.4%. The experimental part of the paper was very detailed, including the reaction process of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Name: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane)

The author of 《Iron-catalysed enantioselective Suzuki-Miyaura coupling of racemic alkyl bromides》 were Iwamoto, Takahiro; Okuzono, Chiemi; Adak, Laksmikanta; Jin, Masayoshi; Nakamura, Masaharu. And the article was published in Chemical Communications (Cambridge, United Kingdom) in 2019. Formula: C12H17BO2 The author mentioned the following in the article:

The first iron-catalyzed enantioselective Suzuki-Miyaura coupling reaction has been developed. In the presence of catalytic amounts of FeCl2 and (R,R)-QuinoxP*, lithium arylborates are cross-coupled with tert-Bu α-bromopropionate in an enantioconvergent manner, enabling facile access to various optically active α-arylpropionic acids including several nonsteroidal anti-inflammatory drugs (NSAIDs) of com. importance. (R,R)-QuinoxP* is specifically able to induce chirality when compared to analogous P-chiral ligands that give racemic products, highlighting the critical importance of transmetalation in the present asym. cross-coupling system. In the part of experimental materials, we found many familiar compounds, such as 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Formula: C12H17BO2)

《Upper-rim functionalization and supramolecular polymerization of a feet-to-feet-connected biscavitand》 was written by Shimoyama, Daisuke; Sekiya, Ryo; Haino, Takeharu. Reference of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020. The article conveys some information:

An octaiodobiscavitand was synthesized via an aromatic Finkelstein iodination reaction in good yield. Sonogashira and Suzuki coupling reactions of the octaiodobiscavitand gave rise to upper-rim-functionalized biscavitands that self-assembled to form a supramol. polymer in the solid state. The results came from multiple reactions, including the reaction of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Reference of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane)

The synthesis of arylboronates by Sandmeyer-type reactions in the presence of water still remains a significant challenge. Herein, we report the use of water-soluble MPA-capped quantum dot (QD) photocatalysts for the borylation of diazonium salts in the presence of water. A biphasic system under mild acidic conditions remains critical to prevent decomposition and competitive disulfide bond formation. The present protocol offers a broader scope of substrates and borylating agents. Addnl., this catalytic system offers a significantly high turnover number (TON). The present methodol. can effectively distinguish subtle reactivity differences between boronic acids and boronates. Mechanistic investigation suggests an excited-state electron transfer pathway.4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Application In Synthesis of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane) was used in this study.

Visceral leishmaniasis (VL), caused by the protozoan parasites Leishmania donovani and Leishmania infantum, is one of the major parasitic diseases worldwide. There is an urgent need for new drugs to treat VL, because current therapies are unfit for purpose in a resource-poor setting. Here, we describe the development of a preclin. drug candidate, GSK3494245/DDD01305143/compound 8, with potential to treat this neglected tropical disease. The compound series was discovered by repurposing hits from a screen against the related parasite Trypanosoma cruzi. Subsequent optimization of the chem. series resulted in the development of a potent cidal compound with activity against a range of clin. relevant L. donovani and L. infantum isolates. Compound 8 demonstrates promising pharmacokinetic properties and impressive in vivo efficacy in our mouse model of infection comparable with those of the current oral antileishmanial miltefosine. Detailed mode of action studies confirm that this compound acts principally by inhibition of the chymotrypsin-like activity catalyzed by the β5 subunit of the L. donovani proteasome. High-resolution cryo-EM structures of apo and compound 8-bound Leishmania tarentolae 20S proteasome reveal a previously undiscovered inhibitor site that lies between the β4 and β5 proteasome subunits. This induced pocket exploits β4 residues that are divergent between humans and kinetoplastid parasites and is consistent with all of our exptl. and mutagenesis data. As a result of these comprehensive studies and due to a favorable developability and safety profile, compound 8 is being advanced toward human clin. trials. In the experiment, the researchers used 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Synthetic Route of C12H17BO2)
