  Palladium-Catalyzed Sequential Cyanation/N-Addition/N-Arylation in One-Pot: Efficient Synthesis of Luotonin A and Its Derivatives

  摘要：

  With the catalysis of palladium, a number of 2-bromo-N-(2-iodobenzyl)benzamides underwent sequential cyanation/N-addition/N-arylation leading to the efficient construction of isoindolo[1,2-b]quinazolin-10(12H)-ones in a two-stage, one-pot manner. This method also allowed the convenient synthesis of luotonin A and its derivatives.

  An interesting procedure for the synthesis of isoindolo[1,2-b]quinazolin-10(12H)-ones has been developed. Starting from commercially available 2-bromoanilines and 2-bromobenzyl amines, with the assistance of a palladium catalyst, the desired products were isolated in good yields. Notably, this procedure proceeded in a highly selective manner; two molecules of CO were incorporated into the substrates
