Abstract

The cyclocondensation of 1,4-dicarbonyl compounds with magnesium nitride as a source of ammonia in methanol allows the synthesis of a diverse array of pyrroles.

Note

We would recommend that the procedure is followed exactly and that appropriate safety screens and worker safety protection is used owing to rapid build-up of pressures during the reaction process.
