Synthesis of 2-oxaadamantane and 1-aryl-2-oxaadamantanes

Abstract The direct reduction of 1-hydroxy-2-oxaadamantanes derivatives to give 2-oxaadamantanes was unsuccessful. 2-Oxaadamantanes could, however, be prepared from 1-hydroxy-2-oxaadamantes by a ring-opening reaction followed by reduction and subsequent ring-closure.
