Oxidative cleavage with lead tetraacetate results in the synthesis of different oxygen heterocycles starting from the same unsaturated 1,2-diol of type I by tuning of the substitution pattern at the angular position. When this compound bears a functional substituent, such as an alkoxy, ester, alkenyl, or simply a hydrogen, more than one reaction pathway are in competition. The process allows for the
用四乙酸铅氧化裂解可通过调节角位置的取代图,从相同的I型不饱和1,2-二醇开始合成不同的氧杂环。当该化合物带有功能性取代基时,例如烷氧基,酯,烯基或仅是氢,竞争的途径不止一个。该过程允许三个不同的复杂的环系的选择性形成,由角度取代基的合适的选择,从而导致无论是环扩展型1,环保留型2或骨牌产品3。
