Abstract: The Lewis acid-catalyzed decarboxylative coupling of cyclic enol carbonates, prepared by the fixation of carbon dioxide onto propargyl alcohols, with silyl enol ethers including ketene silyl acetals, was developed to afford 1,4-dicarbonyl compounds in good-to-high… read more here.

Abstract: Herein, we report a modular α-monoalkylation of cyclic 1,3-dicarbonyls with cyclopropyl alcohols through a cyclic iodonium ylide strategy. This approach is general, base-free, operationally simple, and suitable for various medically important (hetero)cyclic 1,3-dicarbonyls. A wide… read more here.
