Synthesis of new 6-alkylvinyl/arylalkylvinyl substituted 1,2,4-trioxanes active against multidrug-resistant malaria in mice
摘要:
3-Alkyl/arylalkyl substituted 2-butenols 9, 10, 23a-d undergo regiospecific photooxygenation to furnish beta-hydroxyhydroperoxides 11, 12, 24-a-d, respectively, in reasonable yields. Acid catalyzed condensation of 11, 12, 24a-d with various ketones furnish new 1,2,4-trioxanes 13-18, 25a-d, 26a-d, 27a-d in good yields. Several of these trioxanes show promising antimalarial activity against multidrug-resistant Plasmodium yoelii in mice by oral and intramuscular routes. (C) 2004 Elsevier Ltd. All rights reserved.

Geraniol, an abundantly available naturally occurring allylic alcohol, has been used as a starting material to prepare a series of 6-[alpha-(3'-aryl-3-hydroxypropyl)vinyl]-1,2,4-trioxanes. Some of these novel trioxanes have shown very promising antimalarial activity against multi-drug resistant Plasmodium yoelii in mice by both intramuscular (im) and oral routes. (C) 2003 Elsevier Ltd.
