Investigation of aryl halides as ketone bioisosteres: Refinement of potent and selective inhibitors of human cytochrome P450 19A1 (aromatase)
摘要:
Bioisosteric replacement of cyclic ketone functionality with aryl halides was investigated on a centrally-flexible, five-component 1,2,3-triazole-containing pharmacophore, resulting in enhanced inhibition of aromatase (CYP450 19A1). Structure-activity data generated from both syn- and anti- aldol precursors provides significant insights into the requirements for enhanced potency, validating this novel ketoneto-aryl halide bioisostere hypothesis.

anti-aldol products have been synthesized by the enolboration–aldolization of methyl arylacetates in the presence of Chx2BOTf/Et3N at a lower temperature. We report the first example of a complementary syn- and anti-selective enolboration–aldolization of arylacetates.
与苯基乙酸甲酯相反,芳基乙酸甲酯在三氟甲磺酸二环己基硼/三乙胺(Chx 2 BOTf / Et 3 N)介导的烯醇化-醛醇缩合反应中不提供顺式醇醛。然而,需要较小体积的硼试剂(三氟甲磺酸二丁基硼,n- Bu 2 BOTf),较大体积的胺(i- Pr 2 NEt)和环境温度的组合以从芳基乙酸甲酯获得顺式醇醛。在Chx 2 BOTf / Et 3存在下,通过芳基乙酸甲酯的烯醇缩合醛醇化合成了相应的抗醛醇产品。N在较低的温度下。我们报道了芳基乙酸酯的互补的顺式和反选择性烯醇化-醛醇缩合的第一个例子。
