Article abstract of DOI:10.1016/S0040-4039(00)96182-3

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.
