The present invention provides a process for producing a muscone represented by (1) by subjecting a citronellic acid derivative and an undecenoate to a Claisen condensation reaction to produce a keto ester compound represented by (2) decarboxylating the keto ester compound to produce 2,6-dimethyl-8-oxy-2,17-heptadecadiene, cyclizing the heptadecadiene using a metathesis catalyst to produce a 6-dehydromuscone represented by (3) and then hydrogenating the double bond. The present invention also provides the keto ester compound.
