MeOTf-induced carboannulation of alkyl isothiocyanates and aryl alkynes for the synthesis of indenones in good yields under metal-free conditions with C═S bond cleavage is described. The thioalkoxy group at the 3-position of the indenone can also be converted into other functional groups, such as phenyl, methylsulfonyl, amino, and ethoxy groups.
描述了MeOTf诱导的烷基异硫氰酸酯和芳基炔烃的碳环化反应,用于在无金属条件下以C═S键断裂的方式以高收率合成茚满。茚满酮3-位上的硫代烷氧基也可以转化为其他官能团,例如苯基,甲基磺酰基,氨基和乙氧基。
