Palladium chloride-catalyzed intramolecular activation of electroneutral cyclopropane derivatives results in cleavage of the cyclopropane ring followed by formation of heterocyclic derivatives. Phenols, carboxylic acids, and amide groups were considered as substituents ortho to the cyclopropane ring in this catalytic activation chemistry. The regioselectivity observed in the case of amide-containing
电中性环丙烷衍生物的氯化钯催化的分子内活化导致环丙烷环的裂解,随后形成杂环衍生物。在该催化活化化学中,酚,羧酸和酰胺基被认为是环丙烷环邻位的取代基。在含酰胺的底物的情况下观察到的区域选择性与含羧酸的底物的区域选择性不同,排除了简单的环丙烷异构化,然后进行瓦克氧化作为机理途径。[反应:看文字]
