A simple, rapid and green methodology to synthesize cyclic dithiocarbamates (compounds 1-9) was developed by the reaction of 1° amines, CS2 and ethyl 3-bromo-2-oxopropanoate (ethyl bromopyruvate) facilitated by Triton-B as phase transfer catalyst. These compounds (1-9) were characterized with the help of elemental analysis, IR, NMR and mass spectroscopic methods This efficient green approach requires mild conditions and gives good yield of product. In vitro antimicrobial activities of these compounds are reported against the pathogenic bacteria and fungi.

Cow milk oligosaccharides (CMOs) have garnered significant attention due to their association with enhanced infant immune system development, defence against pathogens, and anti-inflammatory properties
