alkene activation and palladium-catalyzed carbonylation was demonstrated as an efficient strategy for the difunctionalization of alkenes. A variety of β-azido carboxylic esters were obtained from mono- and 1,1-disubstituted terminal alkenes with excellent regioselectivities. In addition, the introduced azido group can be reduced to an amine group, providing a facile access to β-amino acid derivatives
已经开发了一种新型的烯烃分子间β-叠氮羰基化反应,其中碘(III)介导的烯烃活化和钯催化的羰基化相结合被证明是烯烃双官能化的有效策略。从单-和1,1-二取代的末端烯烃获得了多种具有优异区域选择性的β-叠氮基羧酸酯。另外,引入的叠氮基可被还原成胺基,提供了从简单烯烃容易地获得β-氨基酸衍生物的途径。
