โฆ Synopsis
Synthesis of an R-deaza analog of the proposed intermediate in the thymidylate synthetase reaction was accomplished from diethyl R-deazafolic acid and an unambiguous proof of the structure is provided. Thymidylate synthetase catalyzes the conversion of 2'-deoxyuridine-5'-monophosphate (dUMP) to thymidine-5'-monophosphate (TMP) in the presence of the cofactor N5,N1'-CH2-tetrahydrofolic acid.l
