Asymmetric Synthesis of (S)-4,5-Difluoro-2-Methylindoline
摘要:
(S)-4,5-Difluoro-2-methylindoline (S)-11 was synthesized effectively by asymmetric reduction of N-[(R)-N-p-tolylsulfonyl]prolinyl-2-(2-oxo)propyl-3,4-difluoroaniilide 4b followed by successive methylsulfonylation and intra-molecular cyclization.
