The catalytic asym. synthesis of borylated 3-hydroxyoxindoles by addition of gem-diborylalkanes to isatins is disclosed. Chiral 3-hydroxyoxindoles bearing two contiguous stereogenic centers were produced in up to >20:1 dr and 99% ee. The synthetic utility of the corresponding products is presented through several transformations of the boryl moiety. This report provides an efficient strategy to incorporate a boryl functional group toward the synthesis of 3-hydroxyoxindoles. In the experiment, the researchers used many compounds, for example, 5-Isopropylindoline-2,3-dione (cas: 150560-58-0Recommanded Product: 5-Isopropylindoline-2,3-dione).
5-Isopropylindoline-2,3-dione (cas: 150560-58-0) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.Recommanded Product: 5-Isopropylindoline-2,3-dione
