Claim:
1. A method for producing a 4-alkyl-3-methylenebutyl carboxylate compound, the method comprising: an acyloxylation step of subjecting a 1-(2-haloethyl)cyclopropyl sulfonate compound represented by General Formula (1): to acyloxylation to obtain a 1-(2-acyloxyethyl)cyclopropyl sulfonate compound represented by General Formula (2): a halogenation step of subjecting the 1-(2-acyloxyethyl)cyclopropyl sulfonate compound (2) to halogenation involving cyclopropyl-allyl rearrangement to obtain a 3-halomethyl-3-butenyl carboxylate compound represented by General Formula (3): and a coupling step of subjecting the 3-halomethyl-3-butenyl carboxylate compound (3) to a coupling reaction with an organometallic reagent represented by General Formula (4): to obtain the 4-alkyl-3-methylenebutyl carboxylate compound represented by Formula (5):
