A green method was developed for the synthesis of chalcones using glycerin as solvent. Subsequently, the potential microbiology activity of these molecules was evaluated by testing them against the Gram-positive bacteria Staphylococcus aureus (S. aureus) ATCC 19095 and Enterococcus faecalis (E. faecalis) ATCC 4083, the Gram-negative bacteria Escherichia coli (E. coli) ATCC 29214 and Pseudomonas aeruginosa (P. aeruginosa) ATCC 9027, and the fungus Candida albicans (C. albicans), which includes ATCC 62342 and three clinical strains of Candida albicans from human oral cavities. The results showed that some chalcones exhibited moderate inhibitory activity, the most prominent being those acting against the fluconazole-resistant strains of Candida albicans.

(E)‐1‐heteroaryl‐3‐arylpropen‐1‐ones. The 13C chemicalshift values (δC) of the chalcone derivatives were determined in order to find if they correlated with the Hammett σ values. A good correlation, especially for the β‐C for both series, was found for the 13C chemicalshift values (δC) of the chalcone derivatives with the Hammett σ values. The chemicalshift values of the β‐C of the heterocyclic compounds
