This work reports a mild and operationally accessible method for synthesizing 1,3-diphenyl-1H-indene derivatives from N-tosylhydrazones and bromobenzhydrols as readily available reactants. Moreover, the cyclization step does not require metal catalysis, the addition of an acid, or a very high temperature. We report a combined experimental and computational study on the mechanism of this cyclization
这项工作报告了一种温和且可操作的方法,用于从N-甲苯磺酰腙和溴苯甲醇作为容易获得的反应物合成 1,3-二苯基-1H-茚衍生物。此外,环化步骤不需要金属催化、添加酸或非常高的温度。我们报告了关于这种环化机制的实验和计算研究。此外,我们通过合成大量产品(甚至是克级产品)以及获得新的生物学相关分子来证明这种方法的实用性。
