Highly convergent modular access to poly-carbon substituted cyclopropanes via Cu(
A conjunctive C-C cross-coupling of cyclopropenes enabled by a Cu-catalyzed three-component reaction of organoboron, cyclopropene and allylic bromide, which featured a modular, stereoselective assembly of poly-carbon substituted cyclopropanes I [R1 = Ph, 4-MeC6H4, 2-naphthyl, etc.; R2 = Me, Ph, 4-MeC6H4, etc.; R3 = Ph, 4-MeC6H4, 3-thienyl, etc.; R4 = H, Me, Br, etc.; R5 = H, F, CH2CH2CH:C(Me)2, etc.; R6 = H, F, Me, etc.] was reported. Preliminary studies showed that the reaction could be extended to benzylation and made enantioselective with C2-sym. bisphosphine ligands. This study involved multiple reactions and reactants, such as 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1Category: ethers-buliding-blocks).
2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: ethers-buliding-blocks
