Simple Total Syntheses of (-)-Ergot Alkaloids and Thier (+)-Enantiomers by a Common Synthesis Method Utilizing Optical Resolution
摘要:
The first and simple total syntheses of (-)-isochanoclavine-I ((-)-1b), (-)-agroclavine ((-)-3), (-)-agroclavine-I ((-)-4), and (-)-norchanoclavine-I ((-)-5C) and their (+)-enantiomers are achieved from indole-3-carboxaldehyde (8) by a common synthesis method utilizing optical resolution. Absolute configuration of (-)-agroclavine-I is determined to be 5R and 10S for the first time. Preparations of both enantiomers of chanoclavine-I (1c) are also included.
