A novel 3-endo-protected hydroxyl-tricyclo[3,2,0,0.sup.2,7 ]-heptan-6-one is described which can be alkylated stereospecifically to give a 5-endo-protected hydroxyl-bicyclo [2,2,1]heptan-2-one which may then be converted via a sequence of reactions into prostaglandins of the F-series having a protecting group at the 9-position. The synthesis of the tricyclo[3,2,0,0.sup.2,7 ]heptan-6-one is also described.
描述了一种新型的3-内保护羟基三环[3,2,0,0.sup.2,7]庚烷-6-酮,可以立体特异性地烷基化,得到一种5-内保护羟基双环[2,2,1]庚烷-2-酮,然后通过一系列反应转化为在9位有保护基的F系列前列腺素。同时也描述了三环[3,2,0,0.sup.2,7]庚烷-6-酮的合成方法。
