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 be

A novel strategy has been developed for the syntheses of (−)-crispine, (−)-benzo[a]quinolizidine, and (−)-salsolidine using (R)-tert-butanesulfinamide as a source of chirality. The approach involves the stereoselective addition of Grignard reag

Claisen rearrangement of bis-O-allylbiphenyl provides mixtures of honokiol (II) and isohonokiol (III) under both conventional and microwave heating conditions.
A stereoselective total synthesis of the 2-(2-hydroxyalkyl)piperidine alkaloids has been accomplished by a Prins–Ritter amidation sequence. Other steps involved in this synthesis are Jacobsen's hydrolytic kinetic resolution (HRK) and ring-closing m
