RegioselectiveS-allylation of thiols with cyclic Baylis–Hillman acetates
摘要:
An efficient and mild S-allylation of thiols with cyclic Baylis-Hillman acetates with no need of a transition-metal-catalyst or an expensive additive is described. Allyl sulfides are prepared in good to excellent yields (60-97%) and a single regioisomer was observed in all cases.[GRAPHICS].
