Abstract
Pyrrole-fused 3-sulfolenes 2a,b were prepared from the corresponding α,β-unsaturated sulfone 1. These pyrroles undergo thermal extrusion of sulfur dioxide to produce highly reactive o-quinodimethanes which can be trapped in Diels-Alder reactions. The resulting pyrroles are important starting reagents in porphyrin synthesis.
