Abstract: A new transition-metal-free 9-azabicyclo[3.3.1]nonan-N-oxyl (ABNO) catalyzed aerobic oxidative synthesis of 2-substituted 4H-3,1-benzoxazines and quinazolines has been developed through cascade reaction of aldehydes with 2-aminobenzyl alcohols and 2-aminobenzylamines, respectively. Under the optimal reaction conditions, the two… read more here.

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.
