A highly stereoselective synthesis of 1-aryl-1,2,3,4-tetrahydroisoquinoline drugs such as solefinacin (muscarinic acetylcholine receptor antagonist) and N-acetyl-1-(4-chlorophenyl)-6,7-dimethoxytetrahydroisoquinoline (AMPA receptor antagonist) has been accomplished using (R)-tert-butanesulfinamide as a chiral source. Chiral tetrahydroisoquinolines have been prepared through the aryl Grignard addition to chiral N-sulfinylimines followed by haloamide cyclization.
