A series of 3-(alkyl and aryl)methylene-2,3-dihydro-1H-isoindol-1-one derivatives was synthesized by a one-pot reaction sequence involving lithiation of 2- (or 3-)halogeno-N-phosphorylmethylbenzamides, cyclization of the aryne intermediate, metal migration and Horner reaction of the resulting phosphorylated aminocarbanion with selected aromatic and aliphatic aldehydes.
