They are reported for the first time. Their structures have been confirmed by IR, ^1H NMR and elemental analysis. The preliminary toxicity tests indicated that most of them exhibited excellent fungicidal activities. The relationship between the structures and the fungicidal activities of the compounds was discussed.展开更多
Ten thiazoline compounds were synthesized starting from tetrahydrothiazoles.
