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
[EN] The present invention relates to a class of acetylenic compounds, to a method of preparing the acetylenic compounds, and to the polymerisation and therapeutic uses of the acetylenic compounds. The invention particularly relates to compounds containing two acetylenic moieties.
