An efficient metal-free domino reaction leading to structural/electronically divergent 1,2-dihydropyridines from easily accessible propargyl vinyl anilines via N-phenyl 3-aza-Cope sigmatropic rearrangement is reported with good to excellent yields using 1,2-dichlorobenzene as solvent under thermal conditions. Spirocyclic substitution is also tolerated under the present optimized conditions.

使用无金属催化方法合成涉及 N-Phenyl-3-aza-Cope 重排的 1,2-二氢取代苯胺类似物

据报道,使用 1,2-二氯苯作为溶剂,通过 N-苯基 3-氮杂-Cope sigmatropic 重排,从易于获得的炔丙基乙烯基苯胺中产生结构/电子发散的 1,2-二氢吡啶的高效无金属多米诺反应,收率良好至极好在热条件下。在目前的优化条件下,螺环取代也是可以接受的。
