A highly enantio- and diastereoselective intramolecular CH insertion reaction of α-diazo esters has been achieved with the use of dirhodium(II) tetrakis[N-phthaloyl-(S)-tert-leucinate] as a catalyst, providing exclusively cis-2-arylcyclopentane-1-carboxylates in up to 95% ee with no evidence of alkene formation.
通过使用四(二)dir [ N-邻苯二甲酰基- (S)-叔亮氨酸酯]作为催化剂,仅提供顺式-2-高达95%ee的芳基环戊烷-1-羧酸酯,没有烯烃形成的迹象。
