  Synthesis of pyrazolo 3,4-pyrimidine analogues of the potent agent N-4-2-2-amino-4 3-oxo-7-pyrrolo 2,3-pyrimidin-5-yl ethylbenzoyl-L-glutamic acid (LY231514)

  摘要：

  Several pyrazolo[3,4-d]pyrimidine analogues of the potent antitumor agent N-{4-12-(2-amino-4(3H)-oxo-7H-pyrrolo [2,3-d]pyrimidin-5-yl)ethyl]benzoyl}-L-glutamic acid (LY231514, 5) have been prepared. A principal synthetic step proved to be a palladium-catalyzed C-C coupling of the 5-halo-substituted pyrazolo[3,4-d]pyrimidines 12-15 with dimethyl 4-ethynylbenzoyl-L-glutamate (16). An additional pyrazolo[3,4-d]pyrimidine analogue of 5 possessing an isofolic acid bridge unit (-NHCH2-) was prepared by reductive alkylation of diethyl 4-formylbenzoyl-L-glutamate (31) with 2-methyl-5-amino-4(3H)-oxo-7H-pyrazolo[3,4-d]pyrimidine (30). Only compound 26 proved to have in vitro cell growth inhibitory activity.

• Synthesis of 7-Halogenated 8-Aza-7-deaza-2′-deoxyguanosines and Related Pyrazolo[3,4-d]pyrimidine 2′-Deoxyribonucleosides

  The synthesis of 7-bromo and 7-iodo derivatives of 8-aza-7-deaza-2′-deoxyguanosine (2, 3) as well as the halogenated 4-alkoxy derivatives 4 a - c and 5 a - c is described. Glycosylation of the halogenated pyrazolo[3,4-d]pyrimidine anions of 7 a -c or 8 a - c with 2-deoxy-3,5-di-O-(p-toluoyl)-α-d-erythro-pentofuranosyl chloride (9) yields regioisomeric glycosylation products, the N(1)-isomers 10 a - c and 11 a - c as well as the N(2)-compounds 12 a - c. The latter isomers lose their halogen during the glycosylation in the presence of non-anhydrous KOH. Anhydrous conditions (NaH) furnished 10 c, 11 c together with the halogenated N(2)-isomers 13 a,b. Compounds 10 a - c, and 11 a - c were deprotected and converted to the 4-alkoxy nucleosides 4 a - c and 5 a - c. The N(1)-nucleosides 4 c and 5 c were hydrolyzed to give the 7-bromo or 7-iodo derivatives of 8-aza-7-deaza-2′-deoxyguanosines 2 and 3. Different from regular 2′-deoxyribonucleosides the sugar moiety of pyrazolo[3,4-d]pyrimidine 2′-deoxyribonucleosides shows a preferred N-type pucker (3T2) in solution, a conformation which is also detected in the solid state.

  描述了8-氮杂-7-脱氮-2′-去氧鸟苷（2, 3）的7-溴和7-碘衍生物的合成，以及卤化的4-烷氧基衍生物4a-c和5a-c。将7a-c或8a-c的卤化吡唑[3,4-d]嘧啶阴离子与2-去氧-3,5-二-O-(对甲苯酰基)-α-d-赤糖善氟糖氯化物（9）进行糖苷化反应，得到区域异构糖苷化产物，N(1)-异构体10a-c和11a-c，以及N(2)-化合物12a-c。后者异构体在无水氢氧化钾存在下糖苷化时失去卤素。在无水条件下（氢化钠）生成了10c、11c以及卤化的N(2)-异构体13a,b。化合物10a-c和11a-c被去保护并转化为4-烷氧基核糖苷4a-c和5a-c。N(1)-核糖苷4c和5c被水解，得到8-氮杂-7-脱氮-2′-去氧鸟苷的7-溴或7-碘衍生物2和3。与常规的2′-去氧核糖核苷不同，吡唑[3,4-d]嘧啶2′-去氧核糖核苷的糖部分在溶液中显示出优先的N型扭曲（3T2），这种构象在固态中也得到了验证。

  3-bromo-4(5H)-oxopyrazolo [3,4-d]pyrimidin-6-yl methyl sulfoxide or 6-amino-3-bromopyrazolo [3,4-d]pyrimidin-4(5H)-one, and subsequent ammonolysis, also gave 7a. The structural assignment of 7a was on the basis of spectral studies, as well as its conversion to the reported guanosine analogue 1d. Application of this glycosylation procedure to 6-(methylthio)-4(5H)-oxopyrazolo[3,4-d]pyrimidine-3-carboxamide gave the corresponding
