The synthetic potentialities of cerium(III) chloride are demonstrated by the synthesis of a nine-membered ring heterocycle component of Griseoviridin (3) in optically active form. The key step involves the stereospecific formation of the alpha-carbalkoxy alkenyl sulfide moiety using a combination system of cerium(III) chloride heptahydrate and sodium iodide.
氯化铈(III)的合成潜力已通过光学活性形式的Griseoviridin(3)的九元环杂环成分的合成得到证明。关键步骤涉及使用七水合氯化铈(III)和碘化钠的组合系统立体定向形成α-烷氧基氧基烯基硫醚部分。
