A selective protocol for the synthesis of 2-methylene-3-substituted-2,3-dihydro-1H-inden-1-ones and 2-benzylidene-2,3-dihydro-1H-inden-1-ones has been developed via palladium-catalyzed cyclocarbonylation reactions of arynes with allyl carbonates and carbon monooxide (CO). It is noteworthy that the selectivity of this new route is depended on both substrates and ligands.
已经选择了用于合成2-亚甲基-3-取代的2,3-二氢-1 H-茚满1-酮和2-亚苄基-2,3-二氢-1 H-茚满-1-酮的选择性方案。通过芳烃与碳酸烯丙酯和一氧化碳(CO)的钯催化的环羰基化反应开发而成。值得注意的是,这种新途径的选择性取决于底物和配体。
