Abstract

A study concerning the gold(I)-catalyzed rearrangement of propargylic tert-butylcarbamates into 5-methylene-1,3-oxazolidin-2-ones is described. The mild reaction conditions employed allow the efficient synthesis of a variety of these structures, which would be less conveniently obtained using other reported methods.

Key words
