WebPhosphoromorpholidate intermediates, initially developed by Khorana and Moffatt, 19 have been widely used for the construction of nucleoside diphosphates. The construction of the diphosphate linkage typically involves exposure of a carbohydrate-derived phosphate nucleophile to phosphoromorpholidate electrophile in pyridine solvent. WebThe first two reactions gave the mixed anhydride of trichloroacetic and thymidylic acids (acyl phosphate) as the major product and P 1, P 2 -dithymidine 5"-pyrophosphate as the byproduct. The third reaction proceeded by a more complicated mechanism and mainly led to substituted polyphosphates.
