  CHLOROSULFONATION OF 9-ARYLOCTAHYDROXANTHEN-1,8-DIONES

  摘要：

  The 9-aryloctathydroxanthen-1,8-diones (3, 4-24) were prepared by reaction of cyclohexan-1,3-dione (1) with selected arylaldehydes. The xanthendiones (4-9, 11, 12, 18, 21, 22) were successfully reacted with chlorosulfonic acid, and the crude sulfonyl chlorides were converted into 15 sulfonamides (26-40) for screening as potential pesticides. Attempted chlorosulfonation of the xanthendiones (13-17) was unsuccessful. alpha-Methylcinnamaldehyde was reacted with cyclohexandione (1) to yield the corresponding xanthendione derivative (23). On the other hand, with o-methoxycinnamaldehyde an impure product formed and the p-methoxy isomer afforded the corresponding 2-arylpyran (25). The NMR spectral data of the compounds are briefly discussed.

  1,8-Dioxo-octahydro-xanthenes are easily prepared via the condensation of aldehydes with 1,3-cyclohexadione and/or dimedone using N-sulfonated DABCO as a new and efficient catalyst. This reagent is also efficiently able to catalyze the condensation of aldehydes with barbituric acid leading to 5-arylmethylene-pyrimidine-2,4,6-triones. The structure of the products was characterized by their IR, 1H NMR, and 13C NMR spectroscopy. The present methodology offers several advantages such as ease of preparation and handling of the catalyst, high yields, simple and green procedure, low cost, short reaction times, easy work-up, and preformation of the reaction in the absence of solvent or in water as a green solvent.

  O-Sulfonated poly(4-vinylpyrrolidonium) chloride is prepared from the reaction of poly(4-vinylpyrrolidone) [PVP], as a cheap and commercially available reagent, and neat chlorosulfonic acid at room temperature. A variety of techniques including infrared spectra (IR), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffraction (XRD), pH analysis and Hammett acidity (Ho) were used to characterize this solid acid. This polymeric reagent showed excellent catalytic activity for the synthesis of xanthene derivatives including 1,8-dioxooctahydroxanthenes, 14-aryl-14H-dibenzo[a,j] xanthenes and 12-aryl-8,9,10,12-tetrahydrobenzo[a]xanthen-11-ones under solvent free conditions. The products were formed in excellent yields over short reaction times and the catalyst can be reused several times without any appreciable loss in its activity.

  A new, cheap, and accessible method has been used for the preparation of nano-belts from the chemical decomposition (top-down approach) of a cheap stainless steel screw and found as an efficient magnetically recyclable nanocatalyst for the preparation of quinolines and 1,8-dioxo-octahydroxanthenes under mild reaction conditions. The nano-belts, Fe–Cr–Ni oxide alloy, was prepared in a two-step synthesis and characterized with various instrumental methods. Due to magnetic property of the screw (a ferritic-alloy), the resultant nano-belts is magnetic. Magnetic Fe–Cr–Ni alloy nano-belts were applied toward efficient preparation of quinolines and 1,8-dioxo-octahydroxanthenes under mild conditions. The catalyst could be readily recovered and recycled for several consecutive runs, while it suffers from a very low metal leaching and subsequently efficiency drop.
