Intramolecular Diels–Alder synthesis of 7-aza-α-carboline compounds
摘要:
An efficient, versatile, and scalable route for the synthesis of 7-aza-alpha-carboline compounds is described. The tricyclic system has been prepared from modified pyrazinones using a key intramolecular [4+2] Diels-Alder transformation. (C) 2010 Elsevier Ltd. All rights reserved.
