Clean synthesis of 1,8-dioxooctahydroxanthenes promoted by DABCO-bromine in aqueous media

An efficient procedure is reported for the synthesis of 3,3,6,6-tetramethyl-9-aryl-1,8-dioxooctahydroxanthenes using a one-pot condensation of arylaldehydes and 5,5-dimethyl-1,3-cyclohexandione in the presence of DABCO-bromine (TDB) as an acid catalyst. To the best of our knowledge this is the first time that DABCO-bromine is used as an acid catalyst in aqueous media for this type of reaction. This method provides several advantages such as use of water as solvent, easy and clean synthesis, simple work up and versatility.

SnCl2?2H2O catalyzed one-pot three components synthesis of pyrano[4,3-b]chromenes and chromeno[4,3-b]chromenes

A new green method has been presented for the synthesis of some novel derivatives pyrano[4,3-b]chromenes and chromeno[4,3-b]chromenes based on bio-mass triacetic acid lactone or 4-hydroxycoumarine via a one-pot three components condensation reaction of tr

An expedient and straightforward solvent-free synthesis of 1,8-dioxo-octahydroxanthenes using eco-friendly aluminized polyborate catalyst

The present work deals with a catalytic application of aluminized polyborate as a mild solid acid catalyst for multicomponent synthesis of 1,8-dioxo-octahydroxanthenes under solvent-free condition at 100°C-110°C. It involves selective domino Knoevenagel-M
