Graphical Abstract

Abstract

1,1-Disubstituted tetrahydroisoquinolines (THIQs) and tetrahydro-ß-carbolines (THBCs) are key intermediates in the synthesis of various alkaloid natural products. These 1,1-disubstituted scaffolds are typically constructed via the Pictet–Spengler reaction. The asymmetric catalytic variant of this reaction enables access to stereochemically pure compounds with significant biological properties. This review focuses on recent progress in organocatalyzed and enzyme-catalyzed asymmetric Pictet–Spengler reactions to generate these 1,1-disubstituted motifs.
