Abstract
Altenin, a metabolite of Alternaria Kikuchiana Tanaka, produces the black spot disease on the leaves and fruits of the pear. The optimum conditions for a 200-1. tank culture of this fungus will be described. Altenin has been tentatively deduced as being an ethyl ester of a C7-carboxylic acid. Of the four expected tautomeric structures, the probability of a furanose ring structure will be demonstrated. There is only one asymmetric center in altenin, at the position α to the ethoxycarbonyl group; this belongs to the l-lactic acid configuration.This publication has 6 references indexed in Scilit:
