The Pictet-Spengler cyclization of iminium salts generated in situ from N-(beta-3-indolyl)ethyl substituted amino acid esters and differently substituted aldehydes proceeds with high stereoselectivity to deliver chiral tetrahydro-beta-carbolines with diastereomer ratios up to 98.5:1.5
Optically active tetrahydro-beta-carbolines were synthesized via an (R)-BINOL-phosphoric acid-cataly...
