Blue light-mediated carbene transfer reaction of thioesters with diazoesters: efficient synthesis of tetrasubstituted Z-enol esters

Abstract

A novel and efficient metal-free, blue light-mediated carbene transfer reaction of thioesters with diazoesters has been achieved. This protocol produces a variety of tetrasubstituted Z-enol esters containing aryl sulfur groups in good yields under mild, convenient and catalyst-free conditions.
