Chemoenzymatic preparation of the novel antifolate thymidylate synthase inhibitor N-(4-{N-[(65)-2-methyl-4-oxo-3, 4, 7, 8-tetrahydro-6-cydopenta[#]quinazolin-6-yl]-Ar-(prop-2-ynyl)amino}-benzoyl)-L- glutamic acid and its glutamyl cleavage product

5-Aminoindane was converted in six steps to the cyclopenta[g]quinazoline ketone 13. Condensation of 13 with diethyl 4-aminobenzoyl-L-glutamate, followed by in situ reduction, produced the secondary amine 15. W-Propargylation of 15, followed by deprotection, gave the diacid 17 as a mixture of diastereoisomers. Treatment of 17 with the bacterial enzyme carboxypeptidase G2 resulted in removal of the L-glutamic acid residue from (6/J)-17 to give a chromatographically separable mixture of the monoacid 18 and the antifolate 5 [(65)-17], which was assayed as an inhibitor of thymidylate synthase (Kfpp = 3 nM). Treatment of isolated diacid 5 with carboxypeptidase G2 produced the monoacid 19 in ;. 98% enantiomeric excess. The (65) stereochemistry of compound 19 has been established by X-ray crystal structure determination of the amide derivative 24.
