Abstract

Whereas there are many methods by which polysubstituted 3-arylpyrroles can be prepared,'there are relatively few syntheses of simple 3-arylpyrrole~.~* Of these, the condensation of tmyhethylisocyanide with activated alkenes: the reductive cyclization of 2- arylsuccinonitriles? and the base-induced ring closure of arylvinamidinium saltas have the greatest degree of generality. Pyrrolylacetylenes are a relatively rare class of compound~ ...
