Nuclear magnetic resonance spectra and mosquito repellent properties of some oxazolidine derivatives of 5-methyl-4-hexenal.

Abstract

Seven novel oxazolidines from 5-methyl-4-hexenal were synthesized, characterized, and evaluated in a cloth test system as mosquito repellents. These heterocycles were a homologous series of 3-alkanoyl-2-(4'-methyl-3'-pentenyl)oxazolidines, with substituents at N-3 ranging from acetyl to n-nonanoyl groups. Carbon-13 NMR spectroscopy at 100.6 MHz revealed… (More)
