Catalytic Enantioselective Synthesis of β-Allenyl Boronic Esters by Conjunctive Cross-Coupling with Propargylic Carbonates was written by Aparece, Mark D.;Hu, Weipeng;Morken, James P.. And the article was included in ACS Catalysis in 2019.Category: alcohols-buliding-blocks This article mentions the following:
Enantioselective conjunctive cross-coupling of lithium pinacolborates Li[RB(CH:CH2)pin] with propargylic carbonates R1CCCR22OCO2Me affords chiral β-boryl allenes RCH(OH)CH2CR1:C:CR22 after oxidative workup as the reaction product. The reaction is found to proceed through the intermediacy of dimethoxyboronate complexes that are generated in situ by a strain-induced ligand exchange reaction. In the experiment, the researchers used many compounds, for example, 2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4Category: alcohols-buliding-blocks).
2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Category: alcohols-buliding-blocks
