Alumina-sulfuric acid catalyzed eco-friendly synthesis of xanthenediones

Alumina-sulfuric acid has been developed as a cost-effective, recyclable, heterogeneous solid acid catalyst for the eco-friendly synthesis of 9-aryl-1,8-dioxododecahydroxanthenes and 9-aryl-3,3,6,6-tetramethyl-1,8- dioxooctahydroxanthenes through the cond

Synthesis of some novel barbituric acid and 1,3-cyclohcxancdionc based condensed hetcrocycles

Synthesis of some novel condensed heterocycles based on peripheral barbituric acid/l,3-cyclohcxanedione moieties and central pyran, pyridine and thiin (thiopyran) ring systems has been achieved by the condensation of barbituric acid/l,3-cyclohexanedionc w

Glycerol as a promoting medium for electrophilic activation of aldehydes: Catalyst-free synthesis of di(indolyl)methanes, xanthene-1,8(2H)-diones and 1-oxo-hexahydroxanthenes

Glycerol was used, for the first time, as a green and effective promoting medium for electrophilic activation of aldehydes, and with which, a catalyst-free system for some reactions that conventionally carried out using acid catalysts, such as synthesis o

Chlorosulfonation of 9-aryloctahydroxanthen-1,8-diones

The 9-aryloctahydroxanthen-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. α-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.
