Efficient Synthesis Of Thymidine Boranophosphoramidates Conjugated With Amino Acids

An efficient synthesis of a thymidine boranophosphoramidate prodrug was accomplished using a phosphoramidite approach in high yield. This new class of compounds is designed to have improved antiviral and anticancer advantages conferred by combining the boranophosphate and normal nucleoside amino acid phosphoramidate. Compounds were characterized by MS and P-31 NMR.
