We herein report an Ir-catalyzed enantioselective C(sp3)-H borylation of cyclopropanecarboxamides using a chiral bidentate boryl ligand for the first time. A variety of substrates with α-quaternary carbon centers could be compatible in this reaction to provide β-borylated products with good to excellent enantioselectivities. We have also demonstrated that the borylated products can be used as versatile precursors engaging in stereospecific transformations of C-B bonds, including the synthesis of a bioactive compound Levomilnacipran.
Rhodium-Catalyzed Enantioselective Silylation of Cyclopropyl C?H Bonds
Lee, Taegyo,Hartwig, John F.
, p. 8723 - 8727 (2016/07/21)
Hydrosilyl ethers, generated in situ by the dehydrogenative silylation of cyclopropylmethanols with diethylsilane, undergo asymmetric, intramolecular silylation of cyclopropyl C?H bonds in high yields and with high enantiomeric excesses in the presence of
