Abstract
NEW MATERIAL:2-( 2- Methyl- 2-propenyl )-4- methyl- 2H-5, 6-dihydropyran expressed by formula I.
USE: A lasting flavoring and perfuming agent and a modifier usable for a floral flavoring and perfuming component in a cosmetic, food and drink, health and hygiene and a medicine.
PROCESS: 2-(2-Oxo-propyl)-4-methyl-2H-5,6-dihydropyran of formula II is reacted with methylenetriphenylphosphorane of formula III (Ph is phenyl) or a component capable of forming the methylenetriphenylphosphorane in an inert organic solvent, preferably in the presence of an organic base, at -10W-20°C for 1W20hr to give the compound of formula I in high yield and purity readily.
