Ultrasound mediated synthesis of a few naturally occurring compounds

摘要

synthesis of 2-mehtylheptadecane 1,14-methylpentadecan-3-one 1,6-oxo-1-nonanol 3,5-(Z)-undecenoic acid 4 and 2-tridecanone 5 hav ebeen accomplished utilizing zinc-copper couple catalyzed conjugate addition of #alpha#,#beta#-unsaturated carbonyl compounds under aqueous sonochemical conditions as the key step.
