Process for producing delta-valerolactone derivatives

摘要

A process for producing delta -valerolactone derivatives of general formula (II), (wherein R<1> and R<2> are the same and each represents an alkyl group having 1 to 6 carbon atoms) characterized by catalytically dehydrogenating tetrahydro-2-pyranol derivatives of general formula (I), (wherein R<1> and R<2> are each as defined above) in the presence of a dehydrogenation catalyst.
