Crystallization-induced asymmetric synthesis of conglomerates could be an innovative and powerful tool in the enantioselective preparation of compounds without any chiral auxiliaries but with requirement of appropriate adjustment of the reaction conditions. It is demonstrated that synthesis of the conglomerating chiral oxo-rhenium(V) complex cis-[ReOCl2(P∼O)py] (P∼O = (OCMe2CMe2O)–POCMe2CMe2O(1−)), yielding practically racemate can be made extremely enantioselective by fine-tuning the reaction conditions.
结晶诱导的同系物不对称合成是一种创新而强大的工具,可以在不使用任何手性助剂的情况下对映体选择性地制备化合物,但需要适当调整反应条件。实验证明,通过微调反应条件,可以极高的对映选择性合成可产生外消旋物的同系手性
