摘要

Chiral tetrahydro-β-carbolines represent an important class of heterocycles in organic chemistry. They are structural units in a variety of natural products and important pharmaceuticals (Figure 1)[1] and useful intermediates for constructing several drugs, such as tadalafil.[2] Consequently, efficient methods for the preparation of optically pure tetrahydro-β-carbolines are in great demand. Whereas diastereospecific Pictet–Spengler ...
