An efficient and divergent synthesis of polyol subunits utilizing a phosphate tether-mediated, one-pot, sequential RCM/CM/reduction process is reported. A modular, 3-component coupling strategy has been developed, in which, simple “order of addition” of a pair of olefinic-alcohol components to a pseudo-C2-symmetric phosphoryl chloride, coupled with the RCM/CM/reduction protocol, yields five polyol fragments. Each of the product polyols bears a central 1,3-anti-diol subunit with differential olefinic geometries at the periphery.
报道了一种利用磷酸酯链介导的一锅法、顺序RCM/CM/还原过程的高效、分散的聚醇亚单位合成方法。开发了一种模块化的3组分偶联策略,其中,将一对烯烃-醇组分简单地按顺序加入拟C2对称性磷酰氯中,并结合RCM/CM/还原协议,可以产生五个聚醇片段。每个产物聚醇都带有一个中心的1,3-反式-二醇亚基,在其周围具有不同的烯烃几何构型。
