“…In recent years, a considerable amount of our research program is focused on the development of new methods and use of new reagents for the synthesis of xanthenes derivatives [19][20][21][22][23][24][25]. In continuation of these studies, we have found that BiVO 4 -NPs as a newly reported reagent [26] is efficiently able to catalyze the synthesis of 1,8-dioxo-octahydro xanthenes.…”

BiVO 4 -NPs can be used as a new and efficient nano-catalyst for the promotion of the synthesis of 1,8-dioxo-octahydro xanthenes derivatives. The structures of the products were characterized by their physical properties, comparison with authentic samples and IR, 1 H NMR and 13 C NMR spectroscopy. Easy preparation of the catalyst, mild reaction conditions, easy work-up procedure, excellent yields and short reaction times are some of the advantages of this work.

In this work, succinimidinium hydrogensulfate ([H-Suc]HSO 4 ), as a novel Brønsted acidic ionic liquid is prepared and characterized by studying its FT-IR, 1 H NMR, 13 C NMR, mass and SEM. This reagent can be used as an efficient catalyst for the N-Boc protection of amines at room temperature and neat conditions. This new method consistently has the advantages of excellent yields and short reaction times. Further, this ionic liquid can be recovered and reused for several times.

W-doped ZnO nanocomposite was easily prepared by sol-gel method. The sample was characterized using a variety of techniques including X-ray diffraction, scanning electron microscopy, transmission electron microscopy, inductively coupled plasma and BET surface area measurement. This reagent can be used as an efficient and heterogeneous catalyst for the preparation of 1, 8-dioxo-octahydroxanthenes from aldehydes in ethanol under mild conditions. The structures of the products were characterized by their physical constants, comparison with authentic samples and IR, 1 H NMR and 13 C NMR spectroscopy. Easy preparation of the catalyst, mild reaction conditions, easy workup procedure, excellent yields and short reaction times are some advantages of this work. In addition, in this article and for the first time the preparation of 1, 8-dioxo-octahydroxanthenes from the protected derivatives of aldehydes including oximes, semicarbazones and 1,1-diacetates is reported.
