Four partially protected stereoisomeric cyclopentenetriols 5, 10, 15 and 21 have been prepared by ring-closing metathesis of carbohydrate-derived 1,6-dienes. The presence of a differentiated allylic alcohol in the cyclopentenetriols allows a variety of synthetic transformations, underlining the synthetic use of the prepared cyclopentenetriol derivatives as chiral building blocks.
四个部分保护的立体异构环戊烯三醇5、10、15和21已通过碳水化合物衍生的1,6-二烯的环闭合易位反应制备。环戊烯三醇中存在一个区分的烯丙醇,使其能够进行多种合成转化,强调了制备的环戊烯三醇衍生物作为手性构建模块的合成应用。
