From alpha-carbamoyl-alpha-cyanooxiranes to 3-halogenopyruvamides.
The crystal structures of the first stable alpha-diol from the alpha-halogenopyruvamide series, 3-chloro-2, 2-dihydroxy-3-phenylpropanamide, C(9)H(10)ClNO(3), and three products [3-(4-chlorophenyl)-2-cyano-2,3-epoxypropanamide, C(10)H(7)ClN(2)O(2), 3-bromo-2-cyano-2-hydroxy-3-p-tolylpropanamide, C(11)H(11)BrN(2)O(2), 3-bromo-2-oxo-3-p-tolylpropanamide, C(10)H(10)BrNO(2)] obtained during the systematic synthesis of alpha-halogenopyruvamides are reported. The crystal structures are dominated by hydrogen bonds involving an amide group. The stability of the geminal diol could be ascribed to hydrogen bonds which involve both hydroxyl groups.
