Abstract
NEW MATERIAL:A ketone derivative of formula I (R1, R2 are lower alkyl).
EXAMPLE: 6-Keto-2-p-toluylhept-2-ene.
USE: Medicine having antifungal activity, and an intermediate for the preparation of natural sesquiterpenes.
PROCESS: One of the carbonyl groups of the diketone compound of formula II is converted to thioketal to obtain the monothioketal compound of formula III, which is alkylated to the compound of formula IV. The compound of formula I is prepared by reducing the compound of formula IV, mesylating the resulting alcohol compound of formula V, introducing a double bond with lithium bromide, and removing the ketal from the product.
