Chiral Phosphoric Acid Catalyzed Enantioselective Desymmetrization of 1,4-Dihydropyridines by C(sp(3) )-H Bromination.
Han M, Zhang SQ, Cui X, Wang QW, Li GX, Tang Z. Han M, et al. Angew Chem Int Ed Engl. 2022 May 23;61(22):e202201418. doi: 10.1002/anie.202201418. Epub 2022 Mar 31. Angew Chem Int Ed Engl. 2022. PMID: 35301801
Readily available symmetrical 1,4-DHPs were used as substrates, and the methyl group at the 2- or 6-position of the 1,4-DHP was selectively monobrominated by desymmetrizing enantioselective bromination. The inert C-H bond was converted into a versatile C-Br bond, wh …
