Synthesis of substituted diazino[c]quinolin-5(6H)-ones, diazino[c]isoquinolin-6(5H)-ones, diazino[c]naphthyridin-6(5H)-ones and diazino[c]naphthyridin-5(6H)-ones
Résumé
Substituted diazino[c]quinolin-5(6H)-ones and -isoquinolin-6(5H)-ones, diazino[c]naphthyridin-6(5H)- and -5(6H)-ones were obtained using two synthetic routes: one-pot cross-coupling/cyclization and two-step cross-coupling/KOH-mediated anionic ring closure. The two strategies gave yields in the same order of magnitude and their choice depends on the availability of the starting material.
