Rationally Designed Guanidine and Amidine Fungicides
摘要:
A previous investigation established that compounds containing a guanidinium or amidinium grouping are effective inhibitors of sterol Delta(8)-Delta(7) isomerase and/or Delta(14) reductase activity in plant pathogenic fungi. A binding model for known fungicidal inhibitors of this enzyme has now been used to rationally design further guanidinium or amidinium inhibitors. Three novel classes of chemistry were investigated. The results of biochemical testing against ergosterol biosynthesis in Ustilago maydis (DC) Corda and of in-vivo testing for fungicidal activity against Erysiphe graminis DC f. sp, hordei Marchal (powdery mildew of barley), do much to support the binding model, and compounds with significant fungicidal activity have been found.

complex for 1‐alkylaminopentenes diminishes resolution efficiency. Nevertheless, the relative cyclization rate for the two diastereomeric substrate–catalyst complexes remains in a typical range of 7–10:1. Plausible attractive π interactions between the aryl substituent and either the metal center or the aromatic system of the bis(triarylsilyl)‐substituted binaphtholate ligand may explain increased stability
