Asymmetric Syntheses, VII 1) . Synthesis of Optically Active Aminonitriles The optically active crystalline aminonitriles 3a – n and 4o are obtained from ketones 1a – o , (4 S ,5 S )‐(+)‐5‐amino‐2,2‐dimethyl‐4‐phenyl‐l,3‐dioxane ( 2 ), and hydrocyanic acid. The absolute configuration of the newly formed centers of chirality (* in 3 and 4 ), and the epimer equilibria (table 1) in solution are determined by 1 H NMR spectroscopy.
