Addition of unactivated thiols to epoxides and oxetanes catalyzed by a rhenium-oxo complex
摘要:
A method for synthesizing beta- and gamma-hydroxy thioethers via addition of unactivated thiols to epoxides and oxetanes has been developed. This reaction is proposed to proceed through an unconventional mode of activation of the heterocycles. The transformation is catalyzed by ReO2I(PPh3)(2) affording beta- and gamma-hydroxy thioethers in moderate to excellent yield with excellent regioselectivity. (C) 2014 Elsevier B.V.
