Synthesis of Vinca Alkaloids and Related Compounds. 100. Stereoselective Oxidation Reactions of Compounds with the Aspidospermane and Quebrachamine Ring System. First Synthesis of Some Alkaloids Containing the Epoxy Ring1a
The first syntheses of the alkaloids (−)-mehranine (3), (+)-voaphylline/conoflorine (4), (+)-N a-methylvoaphylline/hecubine (5), and (−)-lochnericine (2) were achieved by stereoselective epoxidation starting from (−)-tabersonine (1), through intermediates with the aspidospermane and quebrachamine sk...

Summary: | The first syntheses of the alkaloids (−)-mehranine (3), (+)-voaphylline/conoflorine (4), (+)-N a-methylvoaphylline/hecubine (5), and (−)-lochnericine (2) were achieved by stereoselective epoxidation starting from (−)-tabersonine (1), through intermediates with the aspidospermane and quebrachamine skeleton. |
