The first total synthesis of the marine natural product metachromin A was accomplished through a convergent synthesis amenable to the preparation of synthetic analogues. The main features of this synthesis are the introduction of the oxygenation at C17 employing a Thiele acetoxylation reaction and a stereoselective Horner-Wadsworth-Emmons coupling of a nonstabilized phosphonate with a methyl ketone
海洋天然产物变色蛋白A的第一个总合成是通过适合合成类似物制备的会聚合成完成的。该合成的主要特征是采用Thiele乙酰氧基化反应在C 17处引入氧合作用,以及未稳定的膦酸酯与甲基酮衍生物的立体选择性Horner-Wadsworth-Emmons偶联,生成所需的(E)-三取代双键。
