摘要：
Disclosed are α-(ω-Cyanoalkanoyl)-γ-butyrolactone represented by the formula:
wherein n represents an integer of 7 to 11,
and a method for producing the same, which comprises reacting ω-cyano fatty acid ester represented by the formula:
NC-(CH₂) n -COOR (II)
wherein R represents an alkyl group having 1 to 4 carbon atoms and n has the same meaning as in the above,
with γ-butyrolactone in the presence of alkali metal alcoholate represented by the formula:
R′OM (III)
wherein R′ represents an alkyl group having 1 to 4 carbon atoms and M represents an alkali metal.
wherein n represents an integer of 7 to 11,
