Abstract

PURPOSE: To obtain the titled substance useful as a perfume substance in high yield under mild reaction conditions through simple operations, by reacting a substituted malonic diester as a raw material with water to give a reaction product, adding again the above-mentioned raw material to the reaction product without separating it and not using subsidiary raw materials, carrying out reaction under heating.
CONSTITUTION: A substituted malonic diester shown by the formula I(R1 is H or organic residue; R2 is organic residue; R3 is lower alkyl residue) is reacted with water under heating at 160W250°C, to give a substituted acetic acid shown by the formula II, which is reacted with the raw material compound shown by the formula I at the same temperature as that of the above-mentioned reaction, to give a compound shown by the formula III. The amount of water used in the reaction is much excess based on the raw material compound, however, when an acid catalyst, e.g., p-toluenesulfonic acid, etc. is used, the amount of water is sufficiently ≤ ten times molar amount of the raw material.
