formation of 1-arylidene-2-tetralones from 2-tetralone and subse- quent Michael addition of a cyclic secondary amine on the alkenone followed by in situ aerial oxidation was developed to produce 2-naphtholMannichbases. A simple microwave-assisted one-pot synthesis of 2-naphtholMannichbases was also carried out under solvent-free conditions from2-naphthol and corresponding aldehydes and amines

demonstrated cytotoxic activity towards murine P388 and L1210 cells as well as human Molt 4/C8 and CEM T-lymphocytes. In general, the related 1-arylidene-2-tetralones 3 possessed lower potencies in these screens than the compounds in series 1 and 4. Approximately, half of the compounds were evaluated against a panel of human tumour cell lines. In this screen, most of the enones were more cytotoxic than the

Active pyrylium intermediates are in situ generated by a Rh-catalyzed vinylic C–H annulation reaction between exocyclic α,β-enones and alkynes, which undergo a base-promoted rearrangement via 1,5-H shift to form 1H-benzo[f]chromenederivatives.
