✦ Synopsis

A Versatile Synthesis of Acridine-1,9-diones.

-Michael addition of alkenes to 2-ethoxycarbonylmethylquinolin-4-one (I) and subsequent PPA-induced cyclization of the thus obtained C-α-alkylated products (cf. (III), (VI)) provides a new and general route to acridine-1,9-diones (cf. (IV), (VII); 6 examples). In some cases, the cyclization is accompanied by partial decarboxylation. - (CHEN,
