substrate scope. The reaction is carried out with a repertoire of substrates under mild conditions and shows high functional group compatibility. Remarkably the reaction is amenable to organometallic ferrocenyl ester and indole methyl esters bearing an acidic NH moiety. Strikingly no trace of amidation product 8 is observed. In particular α-branched amines bearing β-carbonyl synthesized from indole methyl

Palladium-catalyzed intramolecular cyclization of 2-iodobenzamides with a 2-oxoethyl function group on the nitrogen atom moiety is presented, providing an efficient method for the synthesis of 3-acyl isoindolin-1-ones and 3-hydroxy-3-acylisoindolin-1-ones under mild conditions in moderate yields.

unusual adduct, are obtained from the title compounds. 3-Alkoxy-3-benzyl-2-phenylphthalimidines 3 are synthesized. The behaviour of 1, 3-benzylidene-2-phenylphthalimidines (4 and 5), 3-(α-bromobenzylidene)-2-phenylphthalimidines (6 and 7) with respect to bases and the preparation of the open tautomer 13 of 1 and its hydrochloride are described. A hypothetical mechanism about the formation of 1 and
