Abstract
PURPOSE: 4-Decenoic acid that has a carbon-carbon double bond in the position favourable to cyclization is used to prepare a ketone and lactone useful for perfumery or its intermediate in high conversion and selectivity.
CONSTITUTION: The cyclization of 4-decenoic acid in liquid or vapor phase is effected using an acidic catalyst, e.g., inorganic acid as polyphosphoric or sulfuric acid, organic acid as formic or oxalic acid, or solid acid to produce 2-n-pentyl-2- cyclopentene-1-one and γ-decalactone in high yield. The reaction temperature is in the range from room temperature to 100°C.
USE: The ketone is useful for synthetic intermediate of jasmone and the lactone is useful for peach lactone.
