Abstract:
The invention relates to polyketal compounds. The compounds are synthesized by the selective ketalization of oxocarboxylic acids, e.g. keto acids and semialdehydes, and esters thereof with tetrols and higher polyols that products two or more cyclic ketal ester moieties per molecule, wherein the cyclic ketal moieties are situated in a bis-, tris-, or polyketal conformation. The invention further relates to applications of these compounds and subsequent reactions thereof.
