Title:
1- (2-acyloxy ethyl) cyclo propyl = a sulfonate compound and 4-Al kill - 3-methylene butyl = a manufacturing method of carboxylate
Document Type and Number:
Japanese Patent JP6249937
Kind Code:
B2
Abstract:
Provided is a simple, selective and efficient method for producing 4-alkyl-3-methylenebutyl carboxylates such as 7-methyl-3-methylene-7-octenyl propionate. More specifically, provided is, for example, a method for producing a 4-alkyl-3-methylenebutyl carboxylate compound, comprising an acyloxylation step of subjecting a 1-(2-haloethyl)cyclopropyl sulfonate compound (1) to acyloxylation to obtain a 1-(2-acyloxyethyl)cyclopropyl sulfonate compound (2), a halogenation step of subjecting the compound (2) to halogenation involving cyclopropyl-allyl rearrangement to obtain a 3-halomethyl-3-butenyl carboxylate compound (3), and a coupling step of subjecting the compound (3) to a coupling reaction with an organometallic reagent (4) to obtain the 4-alkyl-3-methylenebutyl carboxylate compound (5).
