A series of benzophenone derivatives has been synthesized and evaluated as inhibitors of HIV-1 reverse transcriptase (RT) and the growth of HIV-1 in MT-4 cells. Through the use of the structure-activity relationships within this series of compounds and computational chemistry techniques, a binding conformation is proposed. The SAR also indicated that the major interactions of 1h with the RT enzyme

Substitutedphenols were chemo-selectively reacted with benzoylchloride in presence of aluminumchloride under solvent-free condition to afford the corresponding 2'-hydroxy aryl benzophenones in excellent yields (72-96%). Naphthol benzoylation resulted in lower yields as compared to phenols. Both reactions completed in 5-10 min with quantitative yields providing excellent control over regioselectivity

We report a challenging copper‐catalyzed Cformyl−H arylation of salicylaldehydes with arylboronic acids that involves unique salicylaldehydic copper species that differ from reported salicylaldehydic rhodacycles and palladacycles. This protocol has high chemoselectivity for the Cformyl−H bond compared to the phenolic O−H bond involving copper catalysis under high reaction temperatures. This approach
我们报道了具有挑战性的水杨醛与芳基硼酸的铜催化的C甲酰基-H芳基化反应,其中涉及独特的水杨醛醛铜种类,不同于报道的水杨醛Rhodacycles和palladacycles。与在高反应温度下涉及铜催化的酚式O-H键相比,该方案对C甲酰基-H键具有较高的化学选择性。该方法与广泛的水杨醛和芳基硼酸底物兼容,包括雌酮和咔唑衍生物,可产生相应的芳基化产物。机理研究表明,水杨醛底物的2-羟基基团通过Cu I / Cu II触发水杨醛醛铜络合物的形成/ Cu III催化循环。

benzofuran core through a cascade of copper‐catalyzed processes wherein the key carbon atom comes from the dimethylacetamide (DMA) solvent. Strong evidence for the participation of a Wacker cyclization catalyzed solely by copper is provided, not only in the title reaction from benzophenones but also from 2‐hydroxy‐α‐arylstyrene derivatives.
The synthesis, identification and electrochemical behaviour of ten copper(II) complexes containing 2-hydroxyphenone ligands are reported. The reduction of the copper(II) complexes follow the same trend as the reduction of the free ligands. The first reduction of the copper(II) complexes is metal based and occur at a potential more than 1 V more positive than the reduction of the free ligand. Linear
报道了十种含有 2-羟基苯酮配体的铜 (II) 配合物的合成、鉴定和电化学行为。铜 (II) 配合物的还原遵循与游离配体还原相同的趋势。铜 (II) 配合物的第一次还原是基于金属的,并且发生在比游离配体还原高 1 V 以上的电位下。在实验值(从实验还原电位获得)和计算化学计算的铜 (II) 配合物的能量之间获得了线性关系。这些线性关系证实了配体和铜之间的良好沟通,可用于预测类似铜 (II) 配合物的还原电位。
