DBU-Promoted Carbonylative Synthesis of 1,3-Oxathiolan-2-ones from Propargylic Alcohols with TFBen as the CO source

Abstract

A DBU-promoted carbonylative cyclization of propargylic alcohols with sulfur has been developed. Various 1,3-oxathiolan-2-ones were produced in 61-98% yields under mild conditions in the absence of metal catalysts. TFBen (benzene-1,3,5-triyl triformate) as an efficient and solid CO surrogate and S8 as an ideal sulfur source were employed and incorporated.
