Recent advances in Aza-Wittig reaction

Recent advances in aza Wittig reaction, including intermolecular, intramolecular and tandem ones , are reviewed. The application of the aza Wittig reactions in synthesis of some N heterocycles, fused heterocycles and natural products are also discussed. Some N containing compounds not easily accessible by other methods were prepared by intermolecular aza Wittig reactions under mild neutral conditions. The efficient intramolecular aza Wittig reaction was also successively utilized in synthesis of five to eight membered heterocycles, including some optically active natural compounds. Many heterocycles, fused heterocycles and natural compounds were prepared via the versatile tandem aza Wittig reaction, such as tandem aza Wittig/heterocumulene mediated annulation, three component tandem aza Wittig reaction, tandem aza Wittig/electrocyclic ring closure, tandem aza Wittig/hetero Diels Alder closure and tandem aza Wittig reaction utilizing bis iminophosphorane.
