The C-6 configuration of (−)-6-methyltetrahydropterin, produced by enzymic reduction of the 7,8-dihydro precursor, is shown to be S by a synthesis. Condensation of 2,4-diamino-5-bromo-6-hydroxypyrimidine with (S)-1,2-propanediamine gave (S)-6-methyltetrahydropterin. Examination of CD spectra of the 6-methyltetrahydropterins from the two origins led to the above conclusion.
通过酶促还原7,8-二氢前体产生的C-6构型(-)-6-甲基四氢蝶呤经合成显示为S。2,4-二氨基-5-溴-6-羟基嘧啶与(S)-1,2-丙二胺的缩合得到(S)-6-甲基四氢蝶呤。对两种来源的6-甲基四氢蝶呤的CD光谱进行检测后得出了上述结论。
