Abstract
NEW MATERIAL:The compound of formulaI(R1 and R2 are H, alkyl or aryl; n is ≥1).
EXAMPLE: 6-Methyl-5-hepten-2-one-N,N-dimethylhydrazone.
USE: A raw material for the preparation of the compound of formula III which is a precursor of the compound of formula II useful as perfumery, etc.
PROCESS: The compound of formulaIis prepared by the condensation reaction of the compound of formula IV[X is halogen or R3SO2O (R3 is alkyl or aryl)]with the compound of formula V in the presence of a basic substance (e.g. alkyl lithium, phenyl lithium, lithium amide, Grignard reagent, etc.). The compound of formulaIcan be converted to the compound of formula III easily, in high yield, by the hydrolysis in the presence of an acid or an oxidizing agent.
