In order to observe the relationship between chemical structure and aroma in γ-butyrolactone derivatives, 27 kinds of γ-methyl-γ-alkylbutyrolactones were prepared by the application of the Grignard reaction between various alkyl halides and ethyl levulinate, twenty of the compounds synthesized being new substances. Majority of them were an aromatic oil but γ-methyl-γ-p-tolyl-, γ-methyl-γ-p-anisyl-, γ-methyl-γ-cyclohexyl-, and γ-methyl-γ-cyclohexylethyl-butyrolactones were obtaind as crystals.
