摘要

Chiral N1-protected vicinal diamines derived from amino acids were condensed with 2- amino-6-chloro-5-nitro-4 (3H)-pyrimidhone, the nitro group reduced, and the amine deprotected. Oxidative cyclization of the resulting triaminopyrimidinone via quinoid pyrimidine intermediates gave a quinoid dihydropteridine, which was then reduced to a tetrahydropteridine C6-stereoisomer. Thus, 6 (R)-and 6 (S)-propyltetrahydropterin were ...
