Isoquinolino-3-sulfolene 7 has been prepared efficiently from 3,4- epoxysulfolene 8. Deprotonation-alkylation reactions proceed smoothly but with low regioselectivity to give substituted isoquinolino-3-sulfolenes. The pyrolysis of these fused 3-sulfolenes at various temperatures provides an easy entry to the corresponding isoquinolino-o-quinodimethanes.
