Highly enantioselective as well as diastereoselective catalytic vinylogous Mannich reactions have been accomplished for the first time with aliphatic straight-chain aldimines and O,O-silylketene acetals and furnish valuable synthetic building blocks in high enantiomeric purity. vinylogous Mannich reaction - phosphoric acid - organocatalyis - contact ion pair - dienolate - BINOL
首次使用脂肪族直链醛亚胺和O,O - O-甲硅烷基乙烯酮缩醛完成了高对映选择性和非对映选择性催化乙烯基曼尼希反应,并以高对映体纯度提供了有价值的合成构件。 乙烯基曼尼希反应-磷酸-有机催化-接触离子对-二烯酸酯-BINOL
