strongly depends on the nature and relative configuration of the substituents in the starting trienic system. In addition, for a productive reaction to be observed, the site of initiation of the metathesis cascade is crucial. The compounds thus obtained may be useful for the synthesis of unusual polydeoxydisaccharides.
                                    描述了使用非应变杂环作为中继部分的第一个RCM-ROM-RCM序列。反应过程很大程度上取决于起始
三烯体系中取代基的性质和相对构型。另外,为了观察到有效的反应,复分解级联的起始位点是至关重要的。如此获得的化合物可用于合成不寻常的聚脱氧二糖。
