Regioselective synthesis of diazaspiro[4.4]nona- and tetrazaspiro[4.5]deca- 2,9-diene-6-one derivatives

(Chemical Equation Presented) Several 1,2-diazaspiro[4,4]nona-2,8-diene-6- one derivatives were synthesised via cycloaddition of nitrilimides to 3-aryliden-2(3H)-furanone derivatives. The formed products react with hydrazine hydrate to give the correspond
