Abstract
A novel pyridine base modified core-shell (γ-Fe2O3@Hap (Hap: Hydroxyapatite)) inorganic-organic hybrid magnetic nanocatalyst has been introduced. The catalyst was fully characterized by spectroscopic analyses (FT-IR, FESEM, EDX, XRD) and its efficiency evaluated as a basic catalyst in one-pot multicomponent reaction of aryl aldehydes, rhodanine and piperidine under ultrasonic irradiation to obtain thiazole derivatives. This green, fast and straightforward protocol produced the products in short reaction times (14-40 min) and high to excellent yields (75-95%).
Keywords: γ-Fe2O3@HAp, thiazole, rhodanine, thiazolone, ultrasonic irradiation, multicomponent reaction.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
