Asymmetric Synthesis of cis-5-tert-Butylproline with Metal Carbenoid NH Insertion
摘要:
The highly stereoselective intramolecular metal carbenoid insertion reaction of sulfinimine-derived delta-amino delta-diazoesters is used to prepare cis-5-tert-butylproline. A concerted or nearly concerted metal carbenoid N-H insertion reaction mechanism is proposed.
