Reacting the 1,2-naphthalenedisulfonimide of (S)-alpha-methylbenzylamine wi
th phenol gave the corresponding alpha-methylbenzyl phenyl ether with 46% e
.e. Synthesis of the authentic optically active phenyl ethers was accomplis
hed under mild, neutral conditions by generating benzyne in the presence of
optically active (R)-alpha-methylbenzyl alcohol. Benzyne was generated by
reacting anthranilic acid with tert-butyl nitrite in refluxing monoglyme. (
