摘要: A facile one-pot benzannulation strategy involving phosphine-3-alkyl allenoate zwitterions and cyclic 1,2-diones is described. The effectively utilized in the synthesis of fluoranthenes benzo[a]aceanthrylenes with impressive photophysical properties. This first report on an intermolecular using a 3-alkyl as four carbon synthon.
