Here, we describe the one-pot assembly of imidazo[1,2-a]pyridine and quinoxaline heterocyclic cores by the electrophilic tandem cyclization between 3,5-diaryl substituted 5-hydroxy-3-pyrrolin-2-ones and the corresponding nitrogen bis-nucleophiles.
A convenient synthesis of fused indolin-3-one derivatives via (3 + 2)-cycloaddition from readily available starting materials has been described.
Novel organotin(IV) complexes of N-acetylated β-amino acids were synthesized and characterized by different techniques. The molecular docking, in vitro α-glucosidase inhibitory, and in vivo antidiabetic activity studies were carried out.
An easy, one-step approach to fluorescent aminomaleimides possessing a build-in linker handle is reported.
A cobalt-catalysed C–H activation of bidentate amides with unsymmetrical 1,3-diynes is reported, in which the regioselectivity of the annulation can be switched by the choice of the diyne alkoxy substituent bulk.
