| Quantitative Structure Activity Relationships of Fungicidally Active Triazoles: Analogs and Stereoisomers of Propiconazole and Etaconazole  | | | | Abstract
| The preparation of the four stereoisomers of propiconazole (TILT®) is described. Their inhibi tion of the 14a-C-demethylation of the sterol nucleus is examined and compared with the inhibi tion by the four stereoisomers of etaconazole (SONAX®). The quantitative structure-activity relationships (Q SAR) of substituted l,3-dioxolane-2-yl-methyltriazoles and l,3-dioxane-2-yl-methyltriazoles on in vivo fungicidal activity are investigated. | | | |

| Inhibition of Ergosterol Biosynthesis by Etaconazole in Ustilago maydis | | | | Abstract
| The triazole fungicide etaconazole (C G A 6 4 251) interferes with the ergosterol biosynthesis in Ustilago m aydis by inhibiting the C-14 dem ethylation o f the sterol nucleus. During the late log growth phase o f U. m aydis a novel endogenous sterol m etabolite (14x-m ethyl-ergosta-8,24(28)-dien-3/?,6a-diol) was discovered and analyzed, which accumulates under the influence o f the fungicide. The structure o f this m etabolite points to a hydroxylation-dehydration m echanism for the introduction o f the double bond at C-5 during the ergosterol biosynthesis. In troduction | | | |

| Strobilurin N and Two Metabolites Related to Chorismic Acid from the Fruit Bodies of Mycena crocata (Agaricales) | | | | Abstract
| Strobilurin N (1), a new member of the strobilurin family of antibiotics, has been isolated from the toadstool Mycena crocata, together with dehydrochorismic acid lactone (5) and 3-[l-carboxyvinyl)oxy]benzoic acid (6), which are closely related to chorismic acid (10). Their structures were determined mainly by 'H and 13C NMR spectroscopy. Interestingly, strobi lurin N is the first strobilurin without antifungal activity | | | |
