Tetraketones with their diversified biological potencies became a highly significant class of oxygen-containing organic compounds. These are prepared by applying a simple Knoevenagel-Michael cascade procedure with 1,3-dicarbonyl compound and aldehydes. In

A novel efficiently mixed transition metal oxides catalytic system with high catalytic activity and heterogeneity constructed of copper and zinc oxide nanoparticles is presented. For preparation of this hybrid catalytic system, carrageenan as a natural polymeric matrix has been chosen to add biocompatibility to the heterogeneous catalyst. Then, the carrageenan textures have been magnetized through the composition with iron oxide nanoparticles. Copper and zinc metallic sites are employed as the main catalytic sites for catalyzing the synthesis of xanthenedione pharmaceutical derivatives from aldehyde and dimedone. Due to the magnetic behavior of the catalyst, the purification process is carried out with high convenience. Herein, a plausible mechanism for the catalytic process is suggested and reusability of the presented catalyst is also investigated. In this report, it has been well-proven that high reaction yields are obtained for xanthenedione derivatives under mild conditions, through applying the presented hybrid catalytic system.
