The solvent-free synthesis of 2-arylideneindan-1,3-diones can be achieved in the presence of MgO or silica gel under grinding. This process is simple, efficient, and environmentally benign. Copyright Taylor & Francis, Inc.
Sulfamic acid-catalyzed, three-component, one-pot synthesis of [1,2,4]Triazolo/benzimidazolo quinazolinone derivatives
Heravi, Majid M.,Derikvand, Fatemeh,Ranjbar, Leila
, p. 677 - 685 (2010)
An efficient and convenient approach is reported for three-component, one-pot synthesis of the [1,2,4]triazolo/benzimidazolo quinazolinones by condensation of 2-amino benzimidazole or 3-amino-1,2,4-triazole as amine sources with dimedone and different ald
Synthesis of highly functionalized indeno[1,2-b]furans
Dutta, Leema,Bhuyan, Pulak J.
, p. 3545 - 3548 (2017)
Some novel functionalized indeno[1,2-b]furans were synthesized from the reaction of indandione/indanone and aldehydes at room temperature followed by the reaction of the Knoevenagel condendensed intermediate with 4-hydroxycoumarins in the presence of iodi

A highly diastereoselective spiro-cyclopropanation reaction of 2-arylidene-1,3-indanediones and dimethylsulfonium ylides has been developedviabase-induced annulation. This efficient and simple protocol features simple operations, mild conditions and excellent functional group compatibility. A variety of structurally interesting spiro-cyclopropanes were prepared in excellent yields and diastereomeric ratios (up to 97% yield and 20?:?1 dr). Also, ring expansion of the cyclopropanation product to quickly deliver a complex indeno[1,2-c]pyridazine structure showcased an interesting application of this method.
Synthesis of 2,3-diaryl-2,3,4,4а-tetrahydro-5Н-indeno[1,2-c]pyridazin-5-ones
