2-aryl-3-(naphthalene-1 or 2-yl)-1,3-thiazolidin-4-ones 4 and 5 were synthesized in 41%─67% yield by using microwave-assisted one-pot protocol. The structures of the new compounds 4l, 4m, 5c, 5e, 5g, 5h, and 5j─5m were confirmed by IR, NMR, MS, and elemental analysis. The antimicrobial activities of the compounds against Pseudomonas syringae pv. lachrymans (Smith et Bryan) Young, Dye & Wilkie, Botrytis cinerea Pers., and Sphaerotheca fusca Blum. were examined. Some of the compounds showed good antifungical activity against Sphaerotheca fusca Blum. |
