from non-conjugated alkenyl amides and ambiphilic organohalides is described. Under PdII/PdIV catalysis, this [n+2] annulation proceeds in an anti-selective fashion and tolerates a wide array of ambiphiles, which are systematically benchmarked with respect to nucleophile identity, electrophile identity, and product ring-size. Otherwise unreactive ambiphilic ortho-haloacetophenones can be activated
描述了从非共轭烯基酰胺和两亲性有机卤化物获得 5、6 和 7 元碳环和杂环的方法。在 Pd II /Pd IV催化下,这种 [ n +2] 环化以反选择性方式进行,并耐受多种双亲剂,这些双亲剂在亲核体特性、亲电子体特性和产物环大小方面进行了系统的基准测试。另外,非反应性两亲性邻卤代
苯乙酮可以使用胺助催化剂来活化。
