Abstract

A new route has been developed toward the preparation of pyrroto-3-sulfolenes, which can be used to generate the corresponding 2,3-dimethylene pyrroles, and their cycloaddition and substitution reactions have been successfully performed. ... Recently, there has been an increasing interest in the study of the preparation and properties of 2,3-dimethylene hetero- aromatics (DMHAs) which are analogues of orthoquinodi- methane 1.1 Although many of this class of reactive ...
