An efficient solvent-free synthesis of 1,8-dioxo-octahydroxanthenes by using Fe2(SO4)3.7H2O as catalyst
Volume 4, Issue 3, pp. 236-358, Serial No. 12 , July 2016, , Pages 273-282
Abstract
A facile and efficient protocol for the synthesis of 1,8-dioxo-octahydroxanthenes has been developed by one-pot Knoevenagel condensation, Michael addition and cyclodehydration reaction of dimedone (active methylene carbonyl compound) with aromatic aldehydes in the presence of Iron (III) sulfate hydrate ...

Sulfamic acid supported on cellulose as a biodegradable and recyclable heterogeneous catalyst for the synthesis of tetrahydrobenzo xanthene derivatives
Volume 4, Issue 2, pp. 133-235, Serial No. 11 , April 2016, , Pages 214-225
Abstract
Cellulose bonded N-propyl diethylene tetra sulfamic acid (CBPDETSA) was successfully applied as a green and recyclable acidic catalyst for the synthesis of tetrahydrobenzo [a] xanthene-11-one as an important class of potentially bioactive compounds. The products are obtained by the coupling of 2-naphtol ... Read More)
