2-oxindoles using diaryl methanols in the absence of an acceptor. A wide array of symmetrical and unsymmetrical diaryl methanols undergoes dehydrogenative coupling with 2-oxindole selectively to generate various substituted 3-(diphenylmethylene)indolin-2-one derivatives in good yields and produces environmentally benign by-products, H2 and H2O. This methodology was successfully applied for the synthesis of

Blue LED-promoted cross-coupling olefination of symmetrical and unsymmetrical 3-arylidene oxindoles has been described from diazoindolones and diphenylmethanethiones. Thermal olefin isomerization and stereoselective synthesis of 3-arylidene oxindoles were also demonstrated in good yield.
蓝色 LED 促进的对称和不对称 3-亚芳基羟吲哚的交叉偶联烯化已从重氮吲哚酮和二苯基甲硫酮中得到描述。还证明了 3-亚芳基羟吲哚的热烯烃异构化和立体选择性合成具有良好的产率。

A synthetic route for the synthesis of C24, as well as for the design of focused libraries of direct AMPK activators was developed based on a convergent strategy. The proposed scheme corresponds to the current trends in C–H bond functionalization. The use of aluminum isopropoxide for the Knoevenagel condensation of oxindole with benzophenones is a noticeable point of this work.
