  Synthesis and chiroptical properties of some abbreviated NAD+ analogues

  摘要：

  Four novel ''abbreviated'' NAD(+) analogues were prepared by the Zincke reaction. The acyclic chain joining the bases of the analogues bears two stereogenic centers with hydroxyl groups in the both erythro and threo mutual relations. The CD spectra of all stereoisomers were measured and discussed.

  Reaction of stereoisomeric 8-bromo-9-(2,3-O-isopropylidene-2,3,4-trihydroxybutyl)adenines (8) with concentrated aqueous ammonia, sodium hydride, potassium tert-butoxide, or 1,8-diazabicyclo[5,4,0]undec-7-ene afforded 4e-O,8-anhydro-9-(2,3-O-isopropylidene-2,3,4-trihydroxybutyl)adenines 9 (derivatives of 1,3-oxazepino[2,3-e]adenine). The CD spectra of optically active stereoisomers of 9 have been studied and it was found that for threo isomers 9a and 9b their character corresponds to 5'-O,8-cycloadenosine. The compounds 9 were also prepared by oxidative cyclization of 9-(2,3-O-isopropylidene-2,3,4-trihydroxybutyl)adenines (7) with lead(IV) acetate in benzene. Reaction of 9-(4-hydroxybutyl)adenine (14) with lead(IV) acetate smoothly afforded the seven-membered ring derivative, 4'-O,8-anhydro-9-(4-hydroxybutyl)adenine (15); no anhydro products with five-, six-, and eight-membered ring were found. 2',3'-O-Isopropylideneinosine (16) reacted with lead(IV) acetate to give 5'-O,8-cyclo-2',3'-O-isopropylideneinosine (17) whereas 9-(4-hydroxybutyl)hypoxanthine (18) afforded no cyclic products.

  立体异构体8-溴-9-(2,3-O-异丙基-2,3,4-三羟基丁基)腺嘌呤（8）与浓氨水、氢化钠、叔丁醇钾或1,8-二氮杂双环[5,4,0]十一烯反应，得到4e-O,8-去水-9-(2,3-O-异丙基-2,3,4-三羟基丁基)腺嘌呤9（1,3-噁唑并[2,3-e]腺嘌呤的衍生物）。对9的光学活性立体异构体的CD光谱进行了研究，发现对于threo异构体9a和9b，它们的特征对应于5'-O,8-环腺苷。化合物9也可以通过9-(2,3-O-异丙基-2,3,4-三羟基丁基)腺嘌呤（7）与醋酸铅（IV）在苯中氧化环化制备而成。9-(4-羟基丁基)腺嘌呤（14）与醋酸铅（IV）反应顺利地得到七元环衍生物4'-O,8-去水-9-(4-羟基丁基)腺嘌呤（15）；没有发现五元、六元和八元环的去水产物。2',3'-O-异丙基核苷（16）与醋酸铅（IV）反应，得到5'-O,8-环-2',3'-O-异丙基核苷（17），而9-(4-羟基丁基)次黄嘌呤（18）没有产生环状产物。
