Molecular iodine‐catalyzed one‐pot synthesis of tetrahydrobenzo[a]xanthene‐11‐one and diazabenzo[a]anthracene‐9,11‐dione derivatives under microwave irradiation

An efficient one-pot condensation of β-naphthol, aldehydes, and cyclic 1,3-dicarbonyl compounds has been achieved with molecular iodine as a catalyst under microwave irradiation, thus a variety of tetrahydrobenzo[a]xanthene-11-one and diazabenzo[a]anthracene-9,11-dione derivatives were prepared in good yields.
