Atropisomeric 5,6-disubstituted-3,4-dihydro-1H-pyridin-2-ones have been synthesized stereoselectively from chiral imines through a Michael reaction and a subsequent stereoselective azacyclization. A thermal study has shown that epimerization of the chiral axis can not take place even at high temperature.
阻转异构的5,6-二取代-3,4-二氢-1 H-吡啶-2-酮已通过手性亚胺通过迈克尔反应和随后的立体选择氮杂环化反应立体合成。热学研究表明,即使在高温下,手性轴的差向异构也不会发生。
