Behaviour of some 1-C-acceptor-substituted glycals under azidohydroxylation conditions.

Azidohydroxylation of 1-carbamoyl, 1-methoxycarbonyl and 1-cyano substituted d-lyxo and d-arabino configured O-peracylated glycals was studied and the reaction conditions were optimized. Under these conditions (3 equiv. NaN/2 equiv.
