Abstract
Etherified 3-hydroxyvalerates of the formula I ##STR1## where R.sub.1 and R.sub.2 are identical or different and are each alkyl of 1 to 12 carbon atoms, cycloalkyl of 5 to 7 carbon atoms, aralkyl of 7 to 10 carbon atoms or aryl of 6 to 10 carbon atoms, are prepared by a process in which a 3-pentenoate of the formula II ##STR2## where R.sub.1 has the above meanings, is reacted with a compound of the formula III R.sub.3 -OH III where R.sub.3 has the same meanings as R.sub.2, at from 30.degree. to 95.degree. C. in the presence of a basic catalyst.

A process for the preparation of an etherified 3-hydroxyvalerate of the formula I ##STR5## and where R.sub.1 and R.sub.2 are identical or different and are each alkyl of 1 to 12 carbon atoms, cycloalkyl of 5 to 7 carbon atoms, aralkyl of 7 to 10 carbon atoms or aryl of 6 to 10 carbon atoms, wherein a 3-pentenoate of the formula II ##STR6## where R.sub.1 has the above meanings, is reacted with a compound of the formula III
- R.sub.3 -OH III
- where R.sub.3 has the same meanings as R.sub.2, at from 30.degree. to 95.degree. C. in the presence of a basic catalyst.
