Zhu, Shengqing published the artcilePhotoredox-catalyzed branch-selective pyridylation of alkenes for the expedient synthesis of Triprolidine, Synthetic Route of 847225-56-3, the publication is Nature Communications (2019), 10(1), 1-7, database is CAplus.
A catalytic, branch-selective pyridylation of alkenes via a sulfinate assisted photoredox catalysis was reported. This reaction proceeded through a sequential radical addition/coupling/elimination, by utilizing readily available sodium sulfinates as reusable radical precursors as well as traceless elimination groups. This versatile protocol allows for the installation of important vinylpyridines with complete branched selectivity under mild conditions. Furthermore, this catalytic manifold was successfully applied to the expedient synthesis of Triprolidine.
