Abstract

Abstract The reactions of readily available vinyl selenones with enantiopure 1, 2-diols, N- protected-1, 2-aminoalcohols, and diamines gave substituted enantiopure 1, 4-dioxanes, morpholines, and piperazines, respectively, in good to excellent yields. The same procedure was extended to the synthesis of thiomorpholine, benzodiazepine, and benzoxazepine. The reactions proceeded in one pot, in the presence of base, through a simple and novel ...
