diyne substituted 2-hydroxy acids and derivatives have been prepared and characterized. Alkylation of butane-2,3-diacetal protected glycolic acid with haloalkyl substituted diyne compounds gave the corresponding diacetal protected diyne substituted 2-hydroxy acids. Diacetal deprotection through acid mediated hydrolysis, transesterification, or aminolysis afforded the 2-hydroxy-diyne acid, ester, or amide
已经制备并表征了一系列二炔取代的2-羟基酸及其衍生物。丁烷-2,3-二缩醛保护的乙醇酸与卤代烷基取代的二炔化合物的烷基化得到相应的二缩醛保护的二炔取代的2-羟基酸。通过酸介导的水解,酯交换或氨基分解作用对二缩醛进行脱保护,分别得到2-羟基-二炔酸,酯或酰胺衍生物。通过2-羟基二炔酸的拓扑化学聚合反应制备了新型的聚二乙炔,并将其与非羟基化的二炔酸的聚合反应进行了比较。
