The present invention provides a method for producing 9,9-dialkoxy-7-noninate and (7E) -7,9-decadienoate useful as intermediates. (9E) -9-oxo-7-nonenoic acid ester (7E) -9-oxo-7-nonenoic acid ester (7E) -9-oxo-7-nonenoic acid ester (3E) -9-oxo-7-nonenoic acid ester 3) and (7E) -7,9-decadiene by (7E) -9-oxo-7-nonenoic acid ester (3) by Wittig reaction with triarylphosphonium = methylide Ar3P = CH2 (4) And (7E) -7,9-decadienoic acid ester production method comprising at least a step of obtaining acid ester (5). The 9,9-dialkoxy-7-nonenoic acid ester (2) is obtained, for example, by a step of reducing the 9,9-dialkoxy-7-nonic acid ester (1). [Chemical 1] [Selected figure] None |
