A catalytic, enantioselective method for the preparation of chiral, non-racemic, alkylboronic esters bearing two vicinal stereogenic centers is described. The reaction proceeds via a 1,2-migration of a zwitterionic thiiranium-boronate complex to give exclusively anti carbosulfenylation products. A broad scope of aryl groups migrate with good yield and excellent enantioselectivity (up to 99:1 e.r.). Similarly, a range of di- and trisubstituted alkenylboronic esters are competent reaction partners. This method provides access to both secondary and tertiary chiral alkylboronic esters. In the experiment, the researchers used many compounds, for example, 2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4SDS of cas: 14204-27-4).
2-(Phenylthio)isoindoline-1,3-dione (cas: 14204-27-4) belongs to indole derivatives. Indole exists overwhelmingly in the 1H-indole form as do other simple indoles. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.SDS of cas: 14204-27-4
