Low-Temperature Reduction by Diisobutylaluminum Hydride in CH2Cl2 of Seven-Membered Lactones from Betulin and S-(+)-Camphor

摘要

The behavior of seven-membered lactones from the triterpenoid betulin and S-(+)-camphor in a novel reaction with organoaluminum compounds was studied using low-temperature reduction of monoterpene sevenmembered lactones by an excess of diisobutylaluminum hydride in CH (2) Cl (2) .
