synthesis of open chain analogue of 1,8-dioxooctahydroxanthene catalyzed by aluminosilicate mcm- 41
Authors
abstract
in this study, aluminosilicate mcm-41 has been found to be an efficient catalyst for reaction betweendifferent benzaldehyde derivatives and 5,5-dimethyl-1,3-cyclohexanedione to give open chain analogue of1,8-dioxo-octahydroxanthene in excellent yields. no evidence for the formation of cyclization products wasobserved. the catalyst can be used several times after recovery.

full textAn efficient green synthesis of highly substituted imidazoles catalyzed by Al-MCM-41 nanoreactors
Al-MCM-41 nanoreactors is found to be a remarkable efficient catalyst for one-pot multicomponent cyclocondensation of benzil, aniline or ammonium acetate and aromatic aldehydes for the synthesis of polysubstituted imidazoles under solvent-free conditions. The reaction was efficiently promoted by 10 mg nano-Al-MCM-41 and the heterogeneous catalyst was recycled for four runs in this reaction with...
