lead to the formation of products which are derived from an “exocyclic methyleneintermediate” analogous to the one formed in the thymidylate synthase reaction. The intermediate has been identified by (a) spectral studies, (b) formation of adducts with dihydropyridine and dihydroquinonline derivatives and (c) its reduction to the corresponding thyminederivative. These results provide chemical precedence

Reaction of 6-aminouracil derivatives with imidazolidines (methylenetetrahydrofolate models), in the presence of acid, gives an exocyclic methyleneintermediate which reacts with nucleophiles present in the mixture or can be reduced to a thyminederivative.
