โœฆ Synopsis


In the course of a program aimed at evaluating the synthetic utility of various heterocyclic compounds, we turned to the sulfolene system (i_) in an effort to prepare suitable precursors (4) which would lead to hetero-substituted divinyl derivatives 3.

Carbamoyl imidazolium salts are demonstrated to act as useful carbamoylation reagents, in reactions with alcohols, phenols, thiols and thiophenols to form carbamates and thiocarbamates under relatively mild conditions. The salts are stable and easily prepared from the corresponding amines using CDI.
