Abstract

Abstract A clean procedure for the synthesis of tetrahydrobenzo [c] xanthenes was established in the presence of a functional ionic liquid, 1-butyl-(4-dimethylamino) pyridinium hydroxide [BDMAP][OH]. The reaction was carried out via the one-pot multi-component condensation of aromatic aldehydes, cyclic 1, 3-dicarbonyl compounds, and α-naphthol in aqueous media, to afford good to excellent yields ranging from 80 to 85% within 60–90 ...
