Because of disorder in the sec-butyl group, the photoreactive isopropyl/(R,S)-sec-butyl diester 3 is able to crystallize as a racemic solid solution in the chiral space group P212121. Irradiation of single crystals of this material leads to products of high optical purity (80% ee). An accompanying process of kinetic resolution leaves the recovered starting material enriched in one of its enantiomers
由于仲丁基基团的无序性,光反应性异丙基/(R,S)-仲丁基二酯3能够在手性空间基团P2 1 2 1 2 1中结晶为外消旋固溶体。辐照此材料的单晶会产生高光学纯度(ee为80%)的产品。伴随的动力学拆分过程使回收的起始原料富含其一种对映异构体。
