Facile and efficient synthesis of xanthenedione derivatives promoted by niobium pentachloride

Abstract

Xanthenedione derivatives were synthesised in one-pot reactions between arylaldehyde derivatives and 1,3-cyclohexanedione promoted by niobium pentachloride. This new method is simple, costeffective, high-yielding with a good variety of substrates generality, and can be conducted within reasonable reaction times.
