Heterogeneous acid catalyzed synthesis and spectroscopic characterization of schiff bases derived from chalcone derivatives

Schiff bases have continued to gain attention as essential building blocks and versatile pharmacophores in drug development and drug-like molecular entities. Thus, the synthesis of Schiff bases was achieved herein via facile acetic acid catalyzed synthetic transformation of chalcones. The targeted Schiff bases and related compounds 2a-m were accessed by the treatment of amines with chalcone 1 which was previously derived through Claisen-Schmidt reaction between benzaldehyde and acetone, at ambient temperature. Structural characterization was achieved via physicochemical properties and the use of IR, UV, 1H and 13C NMR which were spectroscopic techniques. The compounds have essential candidature for further study, in biological activity so as to unleash their medicinal potential.

Diene-transmissive hetero Diels-Alder reaction of cross-conjugated azatrienes with ketenes: A novel and efficient, stereo-controlled synthetic method for hexahydroquinolinones

The cross-conjugated azatrienes, N-aryl-, N-alkyl- or N-dimethylamino-diβ-styrylmethanimines, reacted with diphenylketene and dimethylketene at room temperature to afford [2+2] cycloadducts, while the reaction with dichloroketene produced [4+2] cycloadducts. Upon heating, the [2+2] cycloadducts underwent a [1,3] sigmatropic rearrangement giving the formal [4+2] cycloadducts. The second Diels-Alder reaction of the [4+2] mono-adducts with electron-deficient dienophiles such as tetracyanoethylene, N-phenylmaleimide and methyl vinyl ketone gave hexahydroquinolinone derivatives stereoselectively. The cross-conjugated azatriene bearing different substituents at β- and β′-positions also underwent the diene-transmissive hetero Diels-Alder reaction in a highly site-, regio- and stereo-selective manner.
