C(sp2)H functionalization of pyrrole, indole, indolyl-3-acetic acid (heteroauxin), and 2-amino-3-(indol-3-yl)propionic acid (tryptophan) was carried out via a one-pot C-thiomethylation with formaldehyde and mercaptans in pyridine which simultaneously played the role of a catalyst and solvent. The possibility of the synthesis of structurally diverse sulfanyl methylindoles depending on the nature of the reagents was demonstrated.
