Abstract

Efficient assembly of pyrimido-β-carbolines and, including the bioactive alkaloids rutaecarpine, euxylophoricine A, and deoxyvasicinone (), is reported from suitable aromatic amino acids or corresponding aromatic amino esters and imino-thioethers or in a one-step sequence in moderate to good yields. The key step of this methodology is based on an intramolecular aza-displacement of a methylthio group followed by spontaneous ...
