An unprecedented Pd(II)-catalyzed decarbonylative C–H/C–C activation and annulation reaction, which proceeds via intramolecular cyclization, is reported. This reaction of hydroxynaphthoquinones with disubstituted alkynes provides good yields of substituted alkylidene phthalides, which are the key intermediates for the synthesis of bioactive natural products.

Pd(II)催化的脱羰环化反应合成亚烷基邻苯二甲酰亚胺

据报道,空前的Pd(II)催化的脱羰CH-H / CC活化和环化反应是通过分子内环化进行的。羟基萘醌与二取代炔烃的这种反应提供了高收率的取代亚烷基苯酞,这是合成生物活性天然产物的关键中间体。
