An efficient procedure for the asym. allylic amination of Morita-Baylis-Hillman carbonates I (R = Ph, 2-ClC6H4, 3-MeC6H4, 1-naphthyl, 2-thienyl, etc.) with cyclic imides II (phthalimide, tetrachlorophthalimide, tetrabromophthalimide, cis-hexahydrophthalimide, 1,8-naphthalimide) catalyzed by com. available cinchona alkaloids is reported. It proves to be a facile protocol that affords α-methylene-β-imido esters III with good-to-excellent enantioselectivities (up to 94 % ee) and in high yields (up to 97 %). (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009). In the experiment, the researchers used many compounds, for example, 4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7Computed Properties of C8HBr4NO2).
4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. 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.Computed Properties of C8HBr4NO2
