合成路线1
该中间体在本合成路线中的序号:(XXI)Oxidation of the triamino pyrimidinone system (XX) by means of iodine produced the intermediate ortho-iminoquinone (XXI), which underwent hydrolysis to dione (XXII). Subsequent cyclization of (XXII) under controlled conditions led to the chiral tetrahydrofolic acid (VI). Finally, regioselective N5-formylation of (VI) was accomplished by treatment with formic acid and carbonyl diimidazole.
