the corresponding bis-thiolated indolederivatives. The advantages of the reaction include metal-free, room-temperature, mild reaction conditions and broad functional group compatibility. The reaction proceeds via nucleophilic addition of an alkanethiol to an isonitrile moiety, 5-exo cyclization, followed by nucleophilic addition of an alkanethiol to a 3-alkylidene indole intermediate. Density functional
Diverse 2-sulfonyl- and 2-thiocyanato-3-substituted quinolines were synthesized from o-alkynylisocyanobenzenes by nucleophilic addition of the respective sulfinate sodium salts and ammonium thiocyanate to the isocyanide moiety followed by cyclization. The salient features of the methodology include metal-free, ambient temperature and mild reaction conditions, ease of reagent handling, and broad functional
An efficient synthesis of tetrazolo[1,5‐a]quinolines employing the reaction of o‐alkynylisocyanobenzenes with sodium azide is described. The reaction proceeds through the nucleophilic addition of the azide to the isocyanide and a subsequent by 6‐endo cyclization.
