摘要：

The Michael-type addition of indoles represents one of the most important C-C bonds forming reactions at their C-3 position. Herein, we present a mild, versatile and sustainable protocol for the efficient preparation of beta-indolylketones via a Michael addition between indoles and chalcones or alpha,beta-unsaturated ketones in the presence of substituted arylazo sulfones as photoacid generators (PAGs).
