Abstract
Three compounds, ethyl 5-hydroxy-4, 6-dioxoheptanoate, ethyl 2-methyl-5-hydroxy-5-(1-hydroxyethyl)-4-oxotetrahydrofuroate and 5-phenyl-2-ethoxy-2-(1-hydroxyethyl)-3-oxotetrahy-drofuran, which have structures closely related to altenin, were synthesized from 3-acetoxy-2, 4-dioxopentane. These compounds produced the black spot disease in pears. As these compounds all possess the reductone grouping, it appears that this grouping is responsible for the phytopa-thogenic activity.
