Aryl ketones substituted in ortho, meta, and para position are prepared by a palladium-catalyzed Sonogashira reaction followed by a regioselective hydration of the so-formed alkyne with triflimidic acid or a gold catalyst, under catalytic conditions. This methodology opens a way to obtain substituted aryl alkyl ketones from readily available starting materials, haloarenes, and terminal alkynes. The
通过钯催化的Sonogashira反应,然后在催化条件下,用三氟乙二酸或金催化剂将形成的炔烃进行区域选择性水合,制得邻位,间位和对位取代的芳基酮。该方法学为从容易获得的起始原料,卤代芳烃和末端炔烃中获得取代的芳基烷基酮开辟了道路。介绍了氟哌啶醇,美潘酮,哌帕酮和布洛芬的不同区域异构体的合成。通过多巴胺能和环氧合酶结合试验研究了这些化合物的结构活性关系。
