N-Dealkylation methods are well described for organic chemistry and the reaction is known in nature and drug metabolism; however, to our knowledge, enantioselective N-dealkylation has not been yet reported. In this study, exclusively the (S)-enantiomers o

Starting from tricyclic lactam 2, which is easily accessible by cyclocondensation of δ-oxoester 1 with (R)-phenylglycinol, a three-step synthetic route to enantiopure 1-substituted tetrahydroisoquinolines, including 1-alkyl-, 1-aryl-, and 1-benzyltetrahydroisoquinoline alkaloids, as well as the tricyclic alkaloid (-)-crispine A, has been developed. The key step is a stereoselective α-amidoalkylation reaction using the appropriate Grignard reagent.

Optically active tetrahydroisoquinoline alkaloids, (R)-(+)-higenamine (1R) and (S)-(-)-higenamine (1 S), and their optically active 1-naphthylmethyl analogues (2 and 3), were synthesized by enantioselective hydrogenation of the corresponding dihydroisoqui
