A tandem oxidative dearomatization/intramolecular Diels–Alder reaction: a short and efficient entry into tricyclic system of maoecrystal V
摘要:
A short and efficient route to tricyclic ring system containing bridged bicyclo[2.2.2]octanone annulated with a lactone ring present in the maoecrystal is described. In-situ generation of spiroepoxycyclohexa-2,4-dienone and intramolecular cycloaddition are the key features of our approach. (C) 2010 Elsevier Ltd. All rights reserved.

Synthesis of polycyclic systems related to conidiogenol, crinipellin, and crotogoudin from simple aromatic precursor has been described. Oxidative dearomatization, tandem retro-Diels–Alder/Diels–Alder reaction, and photoreaction are the key features of our approach.
