Bai, Xingfeng published the artcileEnantioselective Palladium-Catalyzed Arylborylation/Cyclization of Alkenes to Access Boryl-Functionalized Heterocyclic Compounds Containing Quaternary Stereogenic Centers, Related Products of dioxole, the publication is Organic Letters (2022), 24(16), 3080-3085, database is CAplus and MEDLINE.
Asym. Pd-catalyzed arylboration/cyclization of both nonactivated and activated alkenes with B2pin2 was developed. A wide range of N-allyl-o-iodobenzamides and o-iodoacryanilides reacted with B2pin2 to afford borylated 3,4-dihydroisoquinolinones and oxindoles, resp., in high yields with high enantioselectivities. The synthetic utility of this enantioselective protocol was highlighted by synthesizing various chiral 3,4-dihydroisoquinolinone and oxindole derivatives containing quaternary stereogenic C centers, including enantioenriched Roche anticancer agent (S)-RO4999200 (no study).
