Recent advances in copper-catalyzed decarboxylative reactions of propargylic cyclic carbonates/carbamates

“…Particularly, the seven-membered triazepine motifs are key structural elements commonly appearing in a series of bioactive natural alkaloids and clinically useful pharmaceuticals, including acetyl-CoA carboxylase inhibitors, acaricides, and herbicides. 17 In this work, solvent dramatically affected the enantioselectivity, and the use of chlorobenzene improved the ee. A plausible catalytic cycle was proposed to elucidate the reaction process (Fig.…”
