folic acid and 5-(CHO)-THF were reductively alkylated with formaldehyde to give 10-methylfolic acid (6) and 5-(CHO)-10-(CH3)-THF (28), respectively. These compounds were tested as inhibitors of the enzymes involved in folate metabolism and for activity against lymphocytic leukemia P388 in mice.
5,6,7,8-四氢叶酸(THF,7)与光气,硫光气和溴化氰反应生成桥连衍生物5,10-(CO)-THF(8),5,10-(CS) -THF(9)和5,10-(C = NH)-THF(11)。10-(氯乙酰基)叶酸(2)的催化加氢得到5,10-(CH 2 CO)-THF(12)。与10-(3-氯丙酰基)叶酸(3)的类似反应得到10-(ClCH2CH2CO)-THF(14),而不是5,10-(CH2CH2CO)-THF(13)。在10-乙氧基叶酸(5)的催化氢化中,初始产物10-(EtO2CCO)-THF(22)容易重排,得到5-(EtO2CCO)-THF(21)。用氯乙酰氯酰化THF,得到N5,N10-二酰化产物(18或19),其不能转化为5,10-COCH2)-THF(17)。分别用乙醛酸和5-羟基戊醛对THF进行还原烷基化,得到5-(HO2CCH2)-THF(24)和5- [HO(CH2)5]
