  Synthesis of benzylaminopyrimidines and their fungicidal activities against wheat brown rust and barley powdery mildew

  摘要：

  Members of a new class of fungicide containing benzyl-aminopyrimidine as a core structure were synthesized and their fungicidal potencies against wheat brown rust, Puccinia recondita, and barley powdery mildew, Erysiphe graminis, were assessed. Among these fungicides, N-(fluoroalkoxy or fluorophenoxybenzyl)-4-pyrimidinamines showed notable preventive activities. The potency of the new pyrimidines was increased when a difluoromethoxy or tetrafluorophenoxy group was introduced at the 4- or 3-position of the phenyl moiety and a methyl or ethyl group was introduced at the benzyl position. Structure-activity relationships are discussed. (C) 1998 Society of Chemical Industry.
