method is reported for the synthesis of 3-(2-aryl-ethylidene)isoindolin-1-ones and 3-(2-arylethylidene)isobenzofuran-1(3H)-ones, proceeding with good to excellent yields and (E:Z) selectivity. This methodology involves the sequential reduction-dehydration reaction of readily obtained 3-(2-oxo-2-arylethyl)isoindolin-1-ones and 3-(2-oxo-2-arylethyl)isobenzofuran-1(3H)-ones followed by a base-catalyzed

A series of 3-(alkyl and aryl)methylene-2,3-dihydro-1H-isoindol-1-one derivatives was synthesized by a one-potreaction 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.
