A series of chiral 1,3‐dioxolanes, 3–12, with >99% ee values, have been synthesized. This is the first study of chiral ketalization reaction starting from ketones with aryl, monosubstituted aryl, and long alkyl chains (C11—AC13). Their ee values were determined by chiral high‐performance liquid chromatography (HPLC) on Chiralcel OD column, using their racemic 1,3‐dioxolanes rac‐3–12, which were also
合成了一系列手性1,3-二氧戊环3 – 12,ee值> 99%。这是从酮与芳基,单取代的芳基和长烷基链(C 11 -AC 13)开始的手性缩酮化反应的首次研究。其EE值通过在Chiralcel OD柱上的手性高效液相色谱法(HPLC)测定,使用它们的外消旋的1,3-二恶戊环外消旋3 - 12,这也被合成为第一次。这些手性和外消旋的1,3-二氧戊环酮通过红外,NMR(1 H,13 C),质谱,元素分析,旋光和手性HPLC进行表征。
