Abstract
Two new (2 and 8) and eight known (1, 3-7, 9 and 10) o-, m-, p-nitro, -methoxy and -methyl substituted chalconoid and alnustone-like compounds with a skeleton of (2E,4E)-1,5-diarylpenta-2,4-dien-1-one (1-10) were synthesized and their 4n(Ï) photocyclization reaction gave 10 new o-, m-, p-nitro, -methoxy and -methyl substituted cis-3-benzoyl-4-phenylcyclobutenes (11-20), stereoselectively, as major products in solution. The antimicrobial activities of all the compounds were also investigated. They showed antibacterial activity against Gram-positive bacteria, moderate antibacterial activity against Gram-negative bacteria, but no antifungal activity was observed against yeast-like fungi.
