Synthesis of the insecticide prothrin and its analogues from biomass-derived 5-(chloromethyl)furfural

Chang, Fei,Dutta, Saikat,Becnel, James J.,Estep, Alden S.,Mascal, Mark

, p. 476 - 480 (2014/02/14)

Prothrin, a synthetic pyrethroid insecticide, was synthesized from the biomass-derived platform chemical 5-(chloromethyl)furfural in six steps and overall 65% yield. Two structural analogues of prothrin were also prepared following the same synthetic approach. Preliminary testing of these furan-based pyrethroids against the yellow fever mosquito Aedes aegypti indicates promising insecticidal activities.
