Pt(II)-catalyzed cycloisomerization of aziridinyl propargylic esters affords 1,2-dihydropyridines with regiodefined installation of substituents. A mild conversion of the 1,2-dihydropyridines to the corresponding substituted pyridines as well as chirality retention from the aziridinyl propargylic ester substrates have been demonstrated.
Pt(II)催化的叠氮基炔丙基丙酸酯的环异构化反应可得到具有区域定义的取代基的1,2-二氢吡啶。已经证明了1,2-二氢吡啶向相应取代的吡啶的温和转化以及从叠氮基炔丙基炔丙基酯底物的手性保留。
