Abstract: Ten novel ureido-substituted 1,3-benzoxazines were synthesized in moderate yields by La(OTf)3-catalyzed reaction of some aldehydes with four ureido-substituted 2-aminomethylphenols which were prepared by a one-pot method. Evaluation of their fungicidal activity revealed that most compounds… read more here.
