摘要
A one-pot, multicomponent reaction of aldehydes, dimedone, and beta-naphthols is described for the preparation of 12-aryl- or 12-alkyl-8,9,10,12-tetrahydrobenzo[alpha]xanthen-11-one derivatives using ammonium chloride as a mild, inexpensive, and environmentally benign catalyst under solvent-free conditions. Different types of aldehyde and beta-naphthol derivatives are used in the reaction, and in all cases the products were synthesized successfully.
