Synthesis and reactions of 2,3,5,6-tetrahydro-2,5-ethano-3-benzazocin-4(1H)-one and a thieno-extended analogue: X-ray structure of 3-methyl-2,3,5,6-tetrahydro-2,5-ethano[1]benzothieno[3,2-d]azocin-4(1H)-one

Organocatalytic stereoselective construction of polycyclic benzo[b]thiophenes from 2-aminobenzo[b]thiophenes and alkynyl-substituted enones

“…2 Compound B demonstrates analgesic activity. 3 As a result, many chemists are committed to developing new protocols to access complex chiral benzo[ b ]thiophenes. 4 Among them, asymmetric organocatalytic annulation of benzo[ b ]thiophene intermediates is an effective way to achieve these goals.…”
