Synthesis and application of chiral triazine condensing reagents prepared from esters of amino acids.

ABSTRACT

Treatment of cyanuric chloride with chiral amines or esters of chiral amino acids gave chiral 2,4-dichloro-6-alkylamino-1,3,5-triazines (2-5) in 49-69% yield, which were found useful as coupling reagents. Enantioselective activation and enantioselective aminolysis in the presence of 2-5 was observed.
