Zhang, Shan-Jun; Cui, Hai-Lei; Jiang, Kun; Li, Rui; Ding, Zhen-Yu; Chen, Ying-Chun published the artcile< Enantioselective Allylic Amination of Morita-Baylis-Hillman Carbonates Catalysed by Modified Cinchona Alkaloids>, COA of Formula: C19H34O2, the main research area is ester unsaturated imido asym synthesis; carbonate ester unsaturated enantioselective allylic amination cyclic imide cinchona.
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 %).
