Catalyzed Asymmetric Diels−Alder Reaction of Benzoquinone. Total Synthesis of (−)-Ibogamine
作者:James D. White、Younggi Choi
DOI:10.1021/ol0001463
日期:2000.7.1
The Diels-Alder addition of diene 2 with benzoquinone catalyzed by (S)-BINOL-TiCl(2) produced cycloadduct 5 in >65% yield and 87% ee. The cycloadduct was transformed into (-)-ibogamine in nine steps (10% overall yield from benzoquinone). A model for the transition state leading to 5 is proposed.
