| abstract | Novel 2,5-dimethyl-3-carbobenzyloxytetrahydrofuran-4-one is prepared by reaction of a lactic acid ester with a crotonic acid ester in the presence of a strong base. Excess lactic acid ester or a solvent which is inert under the reaction conditions is employed. When using an alkyl crotonate, the 2,5-dimethyl-3-carbalkoxytetrahydro-furan-4-one obtained is reacted with benzyl alcohol. The 2,5-dimethyl-3-carbobenzyloxytetrahydrofuran-4-one obtained can be converted by hydrogenation in the presence of noble metal catalysts into the novel 2,5-dimethyl-3-carboxytetrahydrofuran-4-one. The novel compounds obtained have interesting olfactory properties. |
