Hydrogenolysis of mixed ketals of norcamphor by dichloroalane.

The hydrogenolysis of mixed ketals of norcamphor by dichloralane in Et2O leads to the 2-endo-norbornyl alkyl ethers. The stereospecificity is explained by a scheme involving hydride attack from the hexo side on an oxocarbonium ion formed by decompn. of a ketal complexed with dichloroalane to either...
