Abstract

Abstract: A 10-step stereoselective total synthesis of the antimalarial cadinane sesquiterpene (+)-artemisinin (1) is described. Elaboration of (R)-(+)-pulegone to the known sulfoxide 11 was followed by dianion alkylation and desulfurization to provide the trans-2, 3- subtituted cyclohexanone 7. Homologation to the cyclohexenecarboxaldehyde 6 was followed by a diastereoselective silyl anion addition to afford the silyl acetate 15. Tandem ...
