A series of novel 3-(1,3,4-thiadiazolyl)-1,3-benzoxazines were prepared in 47-62% yields from 2-(1,3,4-thiadiazolyl-2-aminomethyl)phenols and CH2Cl2 by phase transfer catalysis reaction for the first time. It was investigated the amount of phase transfer catalyst and reactants, temperature on the yield of the reaction. The structures of the products were characterized by FT-IR, 1H NMR, 13C NMR and elemental analysis. The fungicidal activities of the prepared compounds were also preliminarily evaluated. Most of them displayed moderate fungicidal activity.

Key words: 1,3,4-thiadiazolyl-1,3-benzoxazine, phase transfer catalysis reaction, synthesis, fungicidal activity
