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, cost-effective, high-yielding with a good variety of substrates generality, and can be conducted within reasonable reaction times.
Keywords: niobium pentachloride; Lewis acid; xanthenedione derivatives; one-pot reactions
