Design, synthesis, and herbicidal activity of sec-p-menthane-7-amine derivatives as botanical herbicides.

ABSTRACT: In this study, a series of novel p-menthane type secondary amines (sec-p-menthane-7-amine derivatives 3a-3y) were synthesized and then characterized by FTIR, ¹H NMR, ¹³C NMR, and HRMS. The post-emergence herbicidal activities of these amines against barnyard grass and rape were evaluated by the culture dish method. Most of the sec-p-menthane-7-amine derivatives showed excellent herbicidal activities equivalent to or even higher than either diuron or glyphosate. The alkyl-substituted derivatives were more active than the phenyl-substituted derivatives. The herbicidal activities of compounds 3p, 3r, 3u, and 3w against the root growth of barnyard grass were 404% higher, respectively, than those of glyphosate. The herbicidal activities of compounds 3q
