TL;DR: A series of novel bis-chalcones 3 were prepared by the reaction of 5,5′-methylene-bis-salicylaldehyde 2 with various acetophenones, subsequent treatment with thiourea or guanidine resulted to the corresponding bis-thiazines or bispyrimidines in good yields.

TL;DR: A series of methylene-bis-tetrahydro[1,3]thiazolo[4,5-c]isoxazoles 6 were synthesized by the reaction of chalcone derivative ofmethylene- bis-thiazolidinone 5 with hydroxylamine hydrochloride and the chemical structures were elucidated by IR, 1H, 13C NMR, MS and elemental analyses.

TL;DR: In this article, a series of novel methylene-bis-thiazolidinone derivatives was prepared by condensation of 5-(3-formyl-4-methoxybenzyl)-2-mETHObenzaldehyde 3 with mercapto acids and primary aromatic amines 4 in presence of ZnCl2 under both microwave irradiation and conventional heating conditions.

TL;DR: Characterization of the new compounds has been done by means of IR, 1H NMR, MS and elemental analysis, and the antibacterial, antitubercular and antifungal activity of the compounds has also been evaluated.

TL;DR: A series of novel bis-[3-arylmethylidenimino-1,3-thiazol-4-yl)-4-hydroxy-2H-chromen-2-one-6-yl]-methane compounds synthesized in good yields were found to be the most active against almost all the test bacteria.
