Smooth isoindolinone formation from isopropyl carbamates via bischler-napieralski-type cyclization

Isopropyl carbamates derived from benzylamines provide isoindolinones by treatment with phosphorus pentoxide at room temperature. Utility of this Bischler-Napieralski-type cyclization and a new mechanism involving a carbamoyl cation for rationalization of this smooth conversion are discussed.

1,3,4-Trimethyl-2,2'-pyrromethen-5-one and its 1'-methyl derivative; Synthesis, and thermal and photochemical reactivity

Condensation of 1,3,4-trimethyl-1,5-dihydro-2H-pyrrol-2-one, prepared in high yield from 3,4-dimethylpyrrole, with pyrrole-2-carboxaldehyde and 1-methylpyrrole-2-carboxaldehyde gives a mixture of Z- and E-1,3,4-trimethyl-2,2'-pyrromethen-5-one (7 and
