The rhodium-catalyzedaddition reactions of trimethyl(phenyl)stannane and sodium tetraphenylborate to N-phenylsulfonyl aldimines RCHNSO2Ph (R=alkyl and aryl) provided R(Ph)CHNHSO2Ph in high yields. A cationic and free phosphine complex [Rh(cod)(MeCN)2]BF4 was found to be an efficient catalyst for the addition of PhSnMe3, whereas [Rh(cod)(MeCN)2]BF4/dppb catalyzed the addition of Ph4BNa to various

We report herein an original and rapid synthesis of 2-substituted-4,11-dimethoxy-1-(phenylsulfonyl)-2,3-dihydro-1H-naphtho[2,3-f]indole-5,10-diones by TDAE mediated synthesis of N-benzylsulfonamides followed by an intramolecular N-arylation using Cu-catalyzed system.
