An efficient straightforward metal free domino approach was developed for the synthesis of various 8-hydroxy-2,8-dihydroindeno[2,1-c]pyrazoles via [3 + 2] cycloaddition of substituted alkenes and TsDAM (TosylDiAzoMethane). The salient features of this protocol include high efficiency, mild reaction conditions, greener solvent, metal-free reaction, scalability and broad substrate scope along with high
开发了一种有效的直接无金属多米诺骨牌方法,用于通过取代烯烃和 TsDAM(TosylDiAzoMethane)的 [3 + 2] 环加成合成各种 8-羟基-2,8-二氢茚并[2,1- c ]吡唑。该协议的显着特点包括高效、温和的反应条件、更环保的溶剂、无金属反应、可扩展性和广泛的底物范围以及高区域选择性和产量。
