Abstract

NEW MATERIAL:The 20C diol of formulaI(two Rs are same or different groups of formula II, formula III or formula IV).
EXAMPLE: 2,6,11,15-Tetramethylhexadeca-2,14-diene-7,9-diyne-6,11-diol.
USE: Useful as an intermediate for the preparation of a compound (e.g. crocetane) useful as a cosmetic base, additive for cosmetics and medicines for external use, low-temperature lubricant, and plasticizer for polymers. It is also useful in the field of adhesive, polymer improving agent, etc.
PROCESS: Oxidative coupling reaction of the acetylene alcohols of formula V or their mixture affords the objective compound of formulaI, which can be converted to 6,11-dihydroxycrocetane of formula VI by hydrogenation. The compound of formula VI is also novel, and can be used as it is or after esterification, as a cosmetic base, or additive for cosmetics, medicines for external use, etc.
