４－メチル－５－ノナノン及び４－メチル－５－ノナノールの製造方法
Document Type and Number:
Japanese Patent JP7190422
Kind Code:
B2
Abstract:
The present invention provides a process for preparing 4-methyl-5-nonanone of the following formula (3): the process comprising at least a step of subjecting 2-methylpentanoic anhydride of the following formula (1) and an n-butyl nucleophilic reagent of the following general formula (2) in which M represents Li, MgZ1, or ZnZ1, wherein Z1represents a halogen atom or an n-butyl group, to a nucleophilic substitution reaction to produce 4-methyl-5-nonanone (3), as well as a process for preparing 4-methyl-5-nonanol of the following formula (5), the process comprising at least steps of preparing 4-methyl-5-nonanone; and subjecting the obtained 4-methyl-5-nonanone and a reducing agent to a reduction reaction to produce 4-methyl-5-nonanol (5).
