Pd‐catalyzed intramolecular asymmetric carbopalladation of N‐aryl acrylamides followed by reduction of C(sp3)‐Pd intermediate using diboron–water as a hydride source afforded enantioenriched 3,3‐disubstituted oxindoles in high yields and enantioselectivities. When heavy water was used as a deuterium donor in combination with bis(catecholato)diboron (Cat2B2), deuterium was incorporated into the products
N芳基丙烯酰胺在Pd催化下的分子内不对称碳环合钯,然后使用乙硼酸水作为氢化物源还原C(sp 3)-Pd中间体,从而以高收率和对映选择性提供了对映体富集的3,3-二取代的吲哚。当重水与双(邻苯二酚)二硼(Cat 2 B 2)一起用作氘供体时,氘以高合成效率掺入产品中。配体决定了反应的对映选择性和反应路径,从而提供了氢芳基化(还原性Heck)或碳硼化产物。

The first nickel-catalyzed domino Heck cyclization/Suzukicoupling reaction for the synthesis of 3,3-disubstituted oxindoles bearing quaternary all-carbon centers is reported. A wide range of electrophiles, such as aryl iodides, bromides, triflates, and chlorides, are all compatible with the reaction conditions. Moreover, cheap aryl esters, which undergo catalytic C–O bond cleavage, could also be employed
