A number of synthetic approaches to the (8R)-3,6,7,8-tetrahydroimidazo[4,5-d][1,3]diazepin-8-ol ring system (3) of pentostatin (1) are reported. These involve the synthesis of a number of 4-C-derivatives of N-alkyl-5-amino- and 5-nitro-1H-imidazoles derived from 4-methyl-5-nitro-1H-imidazole.
已报道了戊抑素(1)的(8 R)-3,6,7,8-四氢咪唑并[4,5- d ] [1,3]二氮杂-8-ol环系统(3)的许多合成方法。。这些涉及合成衍生自4-甲基-5-硝基-1 H-咪唑的N-烷基-5-氨基-和5-硝基-1 H-咪唑的多种4- C-衍生物。
