Design, synthesis and effect of the introduction of a propargyloxy group on the fungicidal activities of 1-substituted phenoxypropan-2-amino valinamide carbamate derivatives
introduction of an additional OCH2 linker. The bioassay results indicated that compounds containing a small group at the para-position of phenyl gave excellent fungicidal activities with EC50 values ranging from 0.59 to 2.06 μmol L−1. Most notably, the introduction of a propargyloxy group led to a pronounced increase in the fungicidal activity. Furthermore, compound 7o bearing a propargyloxy group was identified
