A rapid and facile preparation of benzo-[b]-pyran derivatives through condensation of chalcone and 5, 5-dimethyl-1,3-cyclohexandione under microwave irradiation in the presence of catalytic amount of InCl3·4H2O has been developed. With its high efficiency, operational simplicity and environmental benignancy, this method may provide a useful alternative for the preparation of benzo-[b]-pyran derivatives.

Xanthenedione derivatives were prepared through lnCl3·4H2O promoted condensation of aldehydes with 5, 5-dimethyl-1, 3-cyclohexandione in [bmiml[BF4]. The advantages of this method are: simple operation, environmental benign and high efficiency. Moreover, the reaction media and the catalyst can be recovered and reused effectively for at least six times.

The reaction of aromatic aldehydes 1 with 5, 5-dimethyl-1, 3-cyclohexandione 2 was investigated in this paper by using [bmim][BF4] as the reaction medium. It was found that when the reaction was carried out in the presence of catalytic amount of FeCl3·6H2O, xanthenediones 3 was obtained in high yields. On the other hand, when a combination of trimethylchlorosilane (TMSCl) and FeCl3·6H2O was employed as the catalyst, the reaction afforded ring-opening derivatives of xanthenediones 4 with high efficiency.

关键词： FeCl3·6H2O ionic liquids xanthenedione catalysis.
