Abstract: A visible-light-induced radical cascade reaction for the direct alkynylation of tryptamines with alkynyl sulfones was developed, affording a series of C3-alkynyl pyrroloindolines in excellent yields. This method features readily available substrates, good functional group tolerability,… read more here.
