						Aryl-substituted epoxides react with aqueous sodium azide to form a-azidohydrins, NOT B-azidohydrins.  This is according to the following journal references: JOC, 1999, 64, 6094-6096 "Ring Opening of Epoxides with Sodium Azide in Water.  A Regioselective pH-Controlled Reaction" JOC, 1993, 58, 2663-2669 "Acid-Catalyzed Hydrolysis of cis- and trans-Anethole Oxides:  Discrete Carbocation Intermediates and Syn/Anti Hydration Ratios" Thank you
