isoindolinones is described. This novel synthetic strategy involves two catalytic reactions: the ruthenium-catalyzed regioselective alkenylation of aromatic C–H bond of aromatic amides with internal alkynes, and subsequent intramolecular cyclization of the resulting alkene with amide functionalities. The addition of only a catalytic amount of bases is required for efficient construction of the desired
描述了
异吲哚啉酮的选择性和原子经济的合成。这种新颖的合成策略涉及两个催化反应:
钌催化的芳香酰胺与内部
炔烃的芳香C–H键的区域选择性烯基化,以及随后的具有酰胺官能团的烯烃的分子内环化。为了有效地构建所需的
异吲哚啉酮,仅需要添加催化量的碱,并且在串联催化反应中不会形成副产物。在本反应中可以使用各种芳族酰胺和内部
炔烃,并且以良好或高收率获得了在C3位带有季碳的相应的异
吲哚满酮。
