An efficient asymmetric total synthesis of the dimeric macrocyclic diaryl ether phenethyltetrahydroisoquinoline alkaloid (-)-melanthiodine is reported. Key steps of the synthesis include an efficient Noyori asymmetric transfer hydrogenation to access the enantioenriched phenethyltetrahydroisoquinoline monomeric subunit and a copper-mediated cyclodimerization to form the two diaryl ether linkages with concomitant macrocyclization.
Organocatalytic enantioselective pictet-spengler reactions for the syntheses of 1-substituted 1,2,3,4-tetrahydroisoquinolines

A series of 1-substituted 1,2,3,4-tetrahydroisoquinolines was prepared from N-(o-nitrophenylsulfenyl)phenylethylamines through BINOL-phosphoric acid [(R)-TRIP]-catalyzed asymmetric Pictet-Spengler reactions. The sulfenamide moiety is crucial for the rate
