  Synthesis of 3,3-disubstituted oxindoles through Pd-catalyzed intramolecular cyanoamidation

  摘要：

  The cyanoamidation of olefins was achieved. When N-(2-vinylphenyl)cyanoformamides were treated with palladium catalyst, intramolecular cyanoamidation took place to give corresponding 3,3-disubstituted oxindoles. P(t-Bu)(3) showed a remarkable effect on this reaction. When it was used with Pd(dba)(2), the reaction was completed in 15 min at 100 degrees C for many substrates. Furthermore, the enantioselective cyanoamidation was accomplished with Pd(dba)(2) and an optically active phosphoramidite to provide optically active 3,3-disubstituted oxindoles. Manipulation of the resulting oxindoles has been studied. (C) 2010 Elsevier Ltd. All rights reserved.

  The first enantioselective cyanoamidation of olefins provides quick access to a variety of 3,3-disubstituted oxindoles. The combination of Pd(dba)(2), an optically active phosphoramidite, and N,N-dimethylpropylene urea (DMPU) in decalin were found to be the best conditions.
