Synthesis and antimalarial activities of novel 3,3,6,6-tetraalkyl-1,2,4,5-tetraoxanes
摘要:
The oxidative system H2O2/fluorinated alcohol (TFE, HF1P) was used for direct acid- and MeRCO3-catalyzed synthesis of 1,2,4,5-tetraoxanes from cyclic (C6, C7, and C12) and acyclic ketones. The influence of ring size and alkyl chain length were studied and antimalarial activities of synthetic 3,3,6,6-tetraalkyl-1,2,4,5-tetraoxanes were determined. Variations in their antimalarial activities were significant, although they share similar electrochemical properties of the peroxide bond. (c) 2006 Elsevier Ltd. All rights reserved.

A convenient procedure was developed for the synthesis of 1,2,4,5-tetraoxanes based on the reaction of gem-bishydroperoxycycloalkanes with ketals and acetals catalyzed by boron trifluoride etherate, which makes it possible to prepare the target products in yields from 13 to 93%.
