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.
Monoimine Derived from trans-1,2-Diaminocyclohexane and Ethyl Glyoxylate: An Intermediate in Aza-Diels–Alder and Mannich Reactions
摘要:
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.
