The first efficient and regioselective palladium-catalyzed cyclization of internal alkynes and 2-amino-3-iodoacrylates to give moderate to excellent yields of highly functionalized pyrroles has been developed. This approach is applicable to a range of alkynes and affords the deacylated pyrrole under reaction conditions for most substrates. [reaction: see text]
已经开发出第一个有效的且区域选择性的钯催化的内部炔烃和2-氨基-3-碘代丙烯酸酯的环化反应,以产生中等至极高产率的高度官能化的吡咯。该方法适用于多种炔烃,并在反应条件下为大多数底物提供了脱酰吡咯。[反应:看文字]
