A method for the formation of synthetic macrocycles with different ring sizes from diols is presented. Reacting a simple diol precursor with electrophilic reagents leads to a cyclic carbonate, sulfite, or phosphate in a single step in 25–60% yield. Converting the cyclization precursor to a bis-electrophilic iodide or aldehyde enables preparation of a cyclic sulfide and amine, respectively, the latter
提出了一种由二醇形成具有不同环尺寸的合成大环化合物的方法。简单的二醇前体与亲电试剂反应,只需一步即可产生环状碳酸酯,亚硫酸盐或磷酸盐,收率25-60%。将环化前体转化为双亲电子碘化物或醛能够分别制备环状硫化物和胺,后者使用双还原胺化来引起闭环。
