Synthesis of 2,3,6,7-tetrahydro- and 2,3,4,5,6,7-hexahydro-1H-1,4-diazepines via a tandem Michael-type addition–intramolecular aza-Wittig sequence
摘要:
Intramolecular aza-Wittig reaction of azides derived from 1,2-amino azides and alpha,beta-unsaturated ketones leads to 2,3,6,7-tetrahydro-1 H-1,4-diazepines. Reduction of these compounds with lithium aluminium hydride affords the corresponding saturated heterocycles.
