An interesting selectivity-controlled palladium-catalyzed oxidative carbonylation procedure for the synthesis of propiolates and chromenones has been developed. Starting from phenols and alkynes, under slightly different conditions, various propiolates and chromenones can be isolated in moderate to good yields. Additionally, this also presents the first example of direct carbonylative annulation of nonpreactivated phenols and terminal alkynes to produce chromenones.

苯酚和炔烃的选择性控制钯催化羰基合成丙酸酯和ates酮

已经开发了一种有趣的选择性控制的钯催化的氧化羰基化方法，用于合成丙酸酯和色农酮。从苯酚和炔烃开始，在略有不同的条件下，可以以中等到良好的产率分离出各种丙酸酯和色农酮。另外，这也提供了非预活化酚和末端炔烃直接羰基环化以生产色农酮的第一个例子。
