Xie, Peizhong published the artcileCalcium-catalyzed regioselective dehydrative cross-coupling of propargylic alcohols with 1,3-dicarbonyl compounds, Synthetic Route of 517-23-7, the publication is Green Chemistry (2019), 21(19), 5207-5211, database is CAplus.
A novel calcium-catalyzed in situ dehydrative cross-coupling reaction of propargylic alcs. with 1,3-dicarbonyl compounds was developed. This catalytic system can suppress the competitive Meyer-Schuster rearrangement, control regioselectivity, and enable the desired process to occur under solvent-free conditions at room temperature with water as the only byproduct. A variety of vicinal tertiary and all-carbon quaternary centers can be obtained in high yields with broad functional group tolerance.
