cis-aminochromanols are obtained in high yield and with high selectivity over their trans counterparts by hydrogenating the corresponding oximes in the presence of a catalyst and an acid selected from HBr, HCl, and organic sulfonic acid. The cis-aminochromanols can be employed as intermediates in the production of HIV protease inhibitors which are useful for treating HIV infection and AIDS.
