Abstract

Abstract: An efficient total synthesis of (*)-catharanthine (1) has been accomplished. Diels- Alder reaction of 8 with a-chloroacryloyl chloride followed by reaction with MeOH gave 9. Treatment of 9 with Me3SiI gave 10, and reaction of 10 with indole-3-acetyl chloride provided 11, which was converted to 13. Irradiation of 13 in CH3CN/H20 with a 450-W Hanovia mercury lamp through a Pyrex filter provided 14. Reduction of 14 by treatment ...
