  A general strategy for the synthesis of difluoromethyl-containing pyrazoles, pyridines and pyrimidines

  摘要：

  Difluoromethyl-containing heteroannulated pyridines, pyrimidines and pyrazoles are prepared by a two step method. The regioselective cyclizations of electron-excessive aminoheterocycles, hydrazines and amidines with CF2Cl-substituted 1,3-dicarbonyl compounds provide the corresponding CF2Cl-substituted heterocycles. Subsequent radical reactions with trimethylstannane or allyltrimethylstannane gave difluoromethyl-containing heteroannulated pyridines, pyrimidines and pyrazoles, respectively. (C) 2011 Elsevier Ltd.

  The synthesis of 2- and 6-trifluoromethylated purines and 1-deazapurines was performed by formal [3 + 3]-cyclization reactions of 5-aminoimidazoles with a set of trifluoromethyl-substituted 1,3-CCC- and 1,3-CNC-dielectrophiles. The corresponding fluorinated nucleosides were synthesized by glycosylation of 9-unsubstituted purines and 1-deazapurines with peracetylated β-ribose, β-glucose, and rhamnose

  2-和6-三氟甲基化嘌呤和1-deazapurines的合成是通过5-氨基咪唑与一组三氟甲基取代的1,3-CCC-和1,3-CNC-进行正式的[3 + 3]环化反应进行的介电体。相应的氟化核苷是通过9个未取代的嘌呤和1-deazapurines与过乙酰化的β-核糖，β-葡萄糖和鼠李糖进行糖基化合成的，然后进行脱保护。这些支架可以被认为是腺苷脱氨酶（ADA）和肌苷单磷酸脱氢酶（IMPDH）酶的潜在抑制剂。

  The reaction of 5-amino-1H-imidazoles with 3-methoxalylchromone provided a set of imidazo[4,5-b]pyridines (1-des­azapurines) bearing the CO2Me substituent at the α-position of the pyridine core. The corresponding acids were synthesized by subsequent hydrolysis of the ester function. Being typical purine isos­teres, 1-desazapurines are considered to be potent pharmacophores, and are widely used in drug design and medicinal chemistry.

  5-amino-1H-imidazoles 与 3-methoxalylchromone 的反应产生了一组咪唑并[4,5-b]吡啶（1-desazapurines），其吡啶核心的 δ 位带有 CO2Me 取代基。随后通过水解酯功能合成了相应的酸。作为典型的嘌呤异构体，1-desazapurines 被认为是强效药亲和剂，广泛应用于药物设计和药物化学。
