Iodine-Mediated Intramolecular Electrophilic Aromatic Cyclization in Allylamines: A General Route to Synthesis of Quinolines, Pyrazolo[4,3-b]pyridines, and Thieno[3,2-b]pyridines
摘要:
An unprecedented synthesis of aromatic ring annulated pyridines from suitably substituted primary allylamines via intramolecular electrophilic aromatic cyclization mediated by molecular iodine under mild conditions is described.

efficient, regioselective and steresoselecitive one-pot protocol for the synthesis of (Z)-S-2-alkoxycarbonyl-3-acylallyl ethanethioates and (E)-S-2-cyano-3-acylallyl ethanethioates from benzaldehydes and activatedalkenes (methyl acrylate and acrylonitrile) was developed. Our method consisted of Morita–Baylis–Hillman reaction of benzaldehydes and activatedalkenes using DABCO followed by acetylation using
