摘要:
Enantiopure 4-amiiio-3-hydroxymethyl-1,2,3,4-tetrahydroquinolines are synthesized by using an intramolecular cycloaddition of chiral nitrones prepared from aldehydes 5 and (R)-alpha-(hydroxym ethyl)benzylhydroxylamine. Reaction times of the nitrone cycloaddition were optimized by activation under MW-assisted conditions. The absolute configuration of the products was determined by X-ray analysis.
