Abstract:

A series of 2,3-disubstituted-1,3-benzoxazines was synthesized by trimethyl chlorosilane-catalyzed aza-acetalization of 2-arylaminomethyl phenols with aromatic aldehydes. The structures of the prepared compounds were characterized by FT-IR, 1H NMR, 13C NMR and elemental analysis. Fungicidal activities of these compounds were also evaluated. Most of them exhibit good activities. Compound 6e shows 79% and 77.9% activity against S.Scleratotiorum and B.Cinérea, respectively. Compounds 6a and 6d exhibit 74.8% activity against S.Scleratotiorum.

 

Key words: diaryl-benzoxazine, fungicidal activity
