Abstract

The 3‐selenocyanato‐substituted indoles were readily synthesized via (dichloroiodo)benzene (PhICl2)‐induced reaction of 2‐alkynylanilines or 2‐alkenylanilines with KSeCN in MeCN under metal‐free conditions. The reaction sequence was postulated to encompass the formation of a reactive selenocyanogen chloride species, generated in situ from the reaction of PhICl2 and KseCN, followed by electrophilic addition and intramolecular cyclization steps.

Abstract

The selective synthesis of 3‐halogenated quinolin‐2‐ones from N‐arylpropynamides was realized via umpolung process mediated by phenyliodine(III) diacetate (PIDA) and MX (LiCl, LiBr, CuI). Differing from most previous electrophilic cyclization/halogenation processes that afforded spiro[4,5]trienones, 3‐halogenated quinolin‐2‐ones were obtained through this method with high selectivity.
