- Multisulfonate hyperbranched polyglycerol functionalized graphene oxide as an efficient reusable catalyst for green synthesis of benzo[a]pyrano-[2,3-c]phenazines under solvent-free conditions
-
A novel acid catalyst was prepared based on growing hyperbranched polyglycerol (HPG) on the surface of graphene oxide. Then, the hydroxyl groups of HPG on graphene oxide were functionalized by sulfonate groups to form an acid catalyst. The catalyst displayed a good loading level of acidic groups on the surface because of coating graphene oxide with HPG. This new catalyst is demonstrated to be highly effective in the preparation of benzo[a]pyrano[2,3-c]phenazine dyes.

- Multicomponent synthesis of poly-substituted benzo[a]pyrano-[2, 3-c]phenazine derivatives under microwave heating
-
A new one-pot two-step tandem synthesis of highly functionalized benzo[a]pyrano[2, 3-c]phenazine derivatives via microwave-assisted multicomponent reactions of 2-hydroxynaphthalene-1, 4-dione, diamines, aldehydes, and malononitrile is reported. The procedures are facile, avoiding time-consuming and costly syntheses, tedious workup, and purifications of precursors, as well as protection/deprotection of functional groups. The method is expected to find application in the combinatorial synthesis of biologically active compounds, since phenazine and chromene motifs have a broad spectrum of biological activities.
