Abstract

NEW MATERIAL:A camphorene derivative shown by the formula I (R is 1-3C alkyl).
EXAMPLE: 3-(2,2,3-Trimethyl-3-cyclopentene-1-yl)-2-propane.
USE: Aroma, like pine, pineapple, etc. or spices, aroma or flavor component.
PROCESS: A camphorene aldehyde shown by the formula II is subjected to an addition reaction with an alkyl magnesium halide or an alkyl lithium, and hydrolyzed with water or an aqueous solution of diluted acid, to give a compound shown by the formula III. The compound is oxidized with an oxidizing agent, e.g., mixture of sodium dichromate and an aqueous solution of sulfuric acid, etc. to give a compound shown by the formula I.
