PYRROLE AND PYRIDINE DERIVATIVES VIA 1,7-CYCLIZATION OF BUTENYNYL NITRONES THE PRODUCT-DETERMINING INFLUENCE OF SUBSTITUENTS ON THE DEACTIVATION PATHWAY OF THE OXAZA-CYCLOALLENE INTERMEDIATES

A remarkable substituent effect is described for the thermal transformation of three butenynyl nitrones into pyrrole and pyridine derivatives.The results are best explained by assuming oxaza-cycloallenes, cyclopropenes, and, most importantly, carbonyl carbenes as intermediates.
