ABSTRACT:
3-substituted dihydronepetalactone is prepared by deprotonation of nepetalactone and treatment with Grignard reagent to form alkyl and aryl substituted compounds. The compounds so prepared are odorous and have a wide range of utility ranging from insect repellents to fragrance compounds, such as perfumes, among others.
