Abstract
An efficient procedure has been developed for the tandem Michael-aldol self-condensation of delta,gamma-unsaturated beta-ketoesters (1), usi ng sodium benzoate as a mild base catalyst to furnish conjugated vinyl cyclohexenonedicarboxylates (2) some of which show biologic al activit y against ectoparasites in cattle.
