Abstract
Novel ways for preparing the title compounds have been developed. Saturated (1) and unsaturated (2) aldehydoesters, which are easily accessible by a Pd-catalyzed reaction of ethyl 4-bromobenzoate with methallyl alcohol and aldol condensation of ethyl 4-formyl-benzoate with propanal, respectively, are strategically advantageous intermediates for the synthesis. The results of thein vitro assays of some of the synthesized compounds are compared with the known data on their pharmacological effectsin vivo.
