1,2-Benzisothiazol-3(2H)-one (BIT) is one of the most common chemical biocides in industrial products, with a heterocyclic structure and a wide range of antimicrobialactivity. A library of BIT derivatives was synthesized and characterized, from which 18 compounds were selected, tested for anti-bacterial activity relative to the parent molecule and amenable of coupling to plant polysaccharides in general
In one aspect, the present disclosure relates to click-functional antimicrobial molecules (including small molecules or, in some cases, macromolecules) and the construction of antimicrobial polymers such as polyurethanes, polyesters, and polyacrylates, including through the use of such molecules. In some cases, the antimicrobial click-functional molecules are based on 1,2-benzisothiazolin-3-one (BIT), trimethylguanidine or tetramethylguanidine (TMG), polyhexamethylene guanidine (PHMG), fluorine-containing molecules, or a combination thereof. For example, 1,2-benzisothiazolin-3-one (BIT) functionalized with an alkyne (BIT-Al), trimethylguanidine or tetramethylguanidine (TMG) functioned with an alkyne (TMG-Al) or dual alkynes (TMG-dAl), and/or polyhexamethylene guanidine (PHMG) functionalized with an alkyne (PHMG-Al) are described herein. Clickable antimicrobial polymers can be used to form coatings or films.

The base catalyzed ring expansion of 2-substituted 2H-1, 2-benzisoxazolin-3-one (3) to 2-substituted 2H-1, 3-benzoxazin-4-one (4) was observed during the alkylation of 3-hydroxy-1, 2-benzisoxazole (1).
