4-Aza-podophyllotoxin derivatives were synthesized via the three-component reaction of an aldehyde, an aromatic amine, and either tetronic acid or 1,3-indanedione in water under microwave irradiation conditions. This new protocol has the advantages of hig

Condensation of benzene-1,3,5-tricarbohydrazide with benzene-1,4-dicarboxaldehyde generated a new covalent organic framework, COF-ASB (1), in which the organic units are held together via hydrazone linkage to form porous frameworks. COF-ASB (1) is highly crystalline and displays good chemical and thermal stability and is permanently porous. In addition, 1 can be an ideal support to load Ru nanoparticles (Ru NPs) to generate Ru@COF-ASB (2). The obtained composite material is able to highly promote one-pot tandem synthesis of imine products from benzyl alcohols and corresponding amines under solvent-free conditions in air.

Under mechanochemical ball-milling at room temperature, FeCl3 promoted Diels-Alder cycloaddition of styrene with in situ generated N-aryl aldimines in the absence of any solvent afforded exclusively cis-2,4-diphenyltetrahydroquinolines in good to excellent yields within 90 minutes. The isolation work up just involves washing the resulting reaction mixture with water and recrystallization from EtOH-H2O. The advantages of high diastereoselectivity, short reaction time, free use of organic solvent, low cost, employment of cheap, easily available and nontoxic catalyst, and simple work-up procedure make this protocol a very efficient and green alternative to traditional methods for constructing these kinds of heterocyclic skeletons.
