What is Synthesis and Phloem Mobility of Acidic Derivatives of the Fungicide Fenpiclonil about?
## Abstract A series of derivatives of the phenylpyrrole fungicide fenpiclonil was synthesized in which a carboxyl group was present at various sites of this non‐phloem‐mobile molecule. Using the Kleier model, all these acidic analogues were predicted to be moderately phloem‐mobile, especially the __N__‐substituted derivatives. One of these latter molecules, __N__‐carboxymethyl‐3‐cyano‐4‐(2,3‐dichlorophenyl)pyrrole, exhibited some fungicidal activity on the pathogenic fungus __Eutypa lata__, and was then tested as a phloem‐mobile pesticide in the __Ricinus__ system. The compound was indeed mobile in the sieve tubes and was not degraded to fenpiclonil in the phloem sap under our experimental conditions. Its concentration in the sap was closely correlated to the percentage of the undissociated form of the molecule in the external medium, and was similar under acidic conditions (external pH 4.6–5.0) to that of the herbicide glyphosate.
