  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.
