experimental part, p. 725 - 728 (2012/07/28)
Sulfonic-acid-functionalized silica was used as an efficient and recyclable catalyst for the one-pot synthesis of 8-aryl-7,8-dihydro-[1,3]dioxolo[4,5-g] chromen-6-ones with the help of 3,4-methylenedioxyphenol, aldehydes and Meldrums' acid. Different type
CeCl3·7H2O as mild and efficient catalyst for the one-pot multicomponent synthesis of 8-aryl-7,8-dihydro[1,3]dioxolo[4,5-g] chromen-6-ones
Wu, Li-Qiang,Li, Wei-Lin,Yan, Fu-Lin
experimental part, p. 235 - 241 (2011/10/30)
A series of new 8-aryl-7,8-dihydro[1,3]dioxolo[4,5-g]chromen-6-ones were synthesized via a three-component reaction of 3,4-methylenedioxyphenol, aromatic aldehydes and Meldrum's acid in the presence of CeCl3·7H 2O under solvent-free
