Date Mar. 12, 19981,2 and 1,3-dinitrate esters are prepared from polyols containing 1,2- or 1,3-diol fragments using an alkyl or aryl boronic acid to form a cyclic boronate ester derivative which is then reacted with dinitrogen pentoxide to directly generate the dinitrate ester. In the cyclic ester from the 1,2- or 1,3-hydroxyl groups are protected and other reactions may then be carried out on other parts of the molecule of which the fragment form a part, leaving the dinitrate ester to be produced subsequently in the final step. High yields are obtained at both stages. |
