A series of
novel bis-chalcones 3 were prepared by the reaction of
5,5�-methylene-bis-salicylaldehyde 2 with various acetophenones,
subsequent treatment of 3 with thiourea or guanidine resulted to
the corresponding bis-thiazines or bis-pyrimidines in good yields. All
the new compounds have been characterized by IR, 1H NMR, MS
and elemental analysis. The antibacterial, antifungal and
anti-inflammatory activities of the compounds have also been evaluated.
