Copper-catalyzed 6-endo cyclization of N-propargylic β-enaminocarbonyls was developed for the synthesis of oxidation-labile 1,6-dihydropyridines. This synthetic method allows flexible and regio-defined assembly of various substituents at the N1, C2, C3, C4, and C6 positions of 1,6-dihydropyridines under mild conditions.
铜催化的N-炔丙基β-烯胺羰基化合物的6-内型环化反应被用于合成对氧化敏感的1,6-二氢吡啶。这种合成方法能够在温和条件下,在1,6-二氢吡啶的N1、C2、C3、C4和C6位灵活且区域定向地组装各种取代基。
