A new synthesis of (±)-actinidine (1), which relies on intramolecular cycloaddition of an acetylene across a pyrimidine ring, is described. Preparation of 5-(hept-5-yn-2-yl)-4,6-dihydroxypyrimidine (2) followed by thermolysis afforded 1-hydroxyactinidine (13), which could be converted into (±)-actinidine by chlorination and hydrogenation.

This invention provides substituted pyrimidine compounds having the formula:
wherein X is absent, CH2, S, or O, and R is an alkyl group having from one to ten carbon atoms, and optionally salts, hydrates, or solvates thereof, that are useful in treating a patient having a disease or cancer. The compounds of this invention are useful as multi-enzyme antifolates selectively targeting the folate receptor (FR). Further, a method of making 5- and 6-substituted cyclopenta[d]pyrimidine for nonclassical and classical antifolates as TS and DHFR inhibitors is provided.
