Enantioselective Creation of Quaternary Carbon Centers through Addition- Elimination Reaction: Asymmetric Nitroolefination of 3-Substituted 2-Oxindoles
摘要:
Nitroolefination of 3-substituted 2-oxindoles with nitroenamine (5) afforded the corresponding products having quaternary carbon centers with high ee in good yield. Application of this method to concise syntheses of (-)-esermethole (24) and (-)-pseudophrynaminol (28) is described.
