BF3 ⋅ OEt2 Catalyzed Synthesis of 1,3‐Thiazines/‐Selenazines

BF3 ⋅ OEt2 Catalyzed Synthesis of 1,3‐Thiazines/‐Selenazines An efficient strategy for the synthesis of 3,4‐dihydro‐2H‐1,3‐thiazines / 3,4‐dihydro‐2H‐1,3‐selenazines from propargylic alcohols and thioamides/thiosemicarbazones/selenamides is described. The reaction is accomplished in moderate to excellent yield under mild conditions that did not require the exclusion of air or moisture and offers an operationally simplistic and convenient route to the synthetically useful six‐membered N,S/Se‐heterocycles. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Asian Journal of Organic Chemistry Wiley

Abstract

An efficient strategy for the synthesis of 3,4‐dihydro‐2H‐1,3‐thiazines / 3,4‐dihydro‐2H‐1,3‐selenazines from propargylic alcohols and thioamides/thiosemicarbazones/selenamides is described. The reaction is accomplished in moderate to excellent yield under mild conditions that did not require the exclusion of air or moisture and offers an operationally simplistic and convenient route to the synthetically useful six‐membered N,S/Se‐heterocycles.
