Autoxidation of a tetracyclic lactam and its conversion to an enantiopure tertiary alcohol
摘要:
The reduction of chiral tetracyclic lactams 1,2 led to new functionalized derivatives 5-8 containing 3 or 5 stereogenic centers. Autoxidation of compound 5 was observed yielding an enantiopure peroxide 9, which in turn slowly converted into tertiary alcohol 10. (C) 2013 Elsevier Ltd. All rights reserved.

Novel enantiopure policyclic nitrogen heterocycles have been obtained in the diastereoselective aza-Diels-Alder or Mannich reaction of dienes with imine formed in situ from ethyl glyoxylate and (1R,2R)-diaminocyclohexane.
