Different strategies were studied for the preparation of analogues of potent biarylmethanes non-nucleoside reverse transcriptase inhibitors. We undertook the study of the possible routes for the preparation of 3-cyano-4-(3,5-dimethylbenzyl)-5-ethyl-6-hydroxypyridin-2(1H)-one and its cyclic analogue 4-(3,5-dimethylbenzyl)- 6-oxo- 2,3,6,7 - tetrahydrofuro [2,3 - b] pyridine-5 - carboni-trile. Preparation of the former was achieved from the anion of 4-methyl-5-ethyl-2,6-dimethoxynicotinonitrile either by a nucleophilic aromatic substitution reaction on 3,5-dimethyl iodobenzene or starting with a nucleophilic addition reaction on 3,5-dimethylcyclohexanone. Cyclic analogues were prepared by an unprecedented nucleophilic aromatic substitution of, for example, 3,5-dimethyliodobenzene with the dianion of 4-methyl-6-oxo-2,3,6,7-tetrahydrofuro[2,3-b]pyridine-5-carbonitrile. None of the herein described new compounds showed anti HIV-1 activity or cytotoxicity on cellular assays (CEM-SS and MT4).
研究了制备有效联芳基甲烷非核苷逆转录酶抑制剂类似物的不同策略。我们研究了3-氰基-4-(3,5-二甲基苄基)-5-乙基-6-羟基吡啶-2(1H)-酮及其环状类似物4-(3,5)的可能制备路线。 -二甲基苄基)-6-氧代-2,3,6,7-四氢呋喃[2,3-b]吡啶-5-甲腈。前者的制备是由 4-甲基-5-乙基-2,6-二甲氧基烟腈的阴离子通过 3,5-二甲基碘苯上的亲核芳香取代反应或从 3,5-二甲基环己酮上的亲核加成反应开始实现的。环状类似物是通过前所未有的亲核芳族取代制备的,例如 3,5-二甲基碘苯与 4-甲基-6-氧代-2,3,6,7-四氢呋喃[2,3-b]吡啶-二价阴离子5-甲腈。本文描述的新化合物均未在细胞测定(CEM-SS和MT4)中显示出抗HIV-1活性或细胞毒性。
