Asymmetric synthesis of dideazafolate antitumor agents via amidomethylation of nonracemic oxazolidinone imidates, synthesis of LY309887, a cytotoxic dideazafolate analog related to lometrexol

The asymmetric synthesis of LY309887, a cytotoxic dideazatetrahydrofolate analog related to lometrexol, has been accomplished via an application of diastereoselective amidomethylation of a chiral titanium (IV) acyloxazolidinone enolate.
