Photooxygenation of 3-aryl-2-cyclohexenols: synthesis of a new series of antimalarial 1,2,4-trioxanes
摘要:
Using easily accessible 3-aryl-2-cyclohexenols, a photooxygenation route for the preparation of bicyclic 1.2.4-trioxanes is reported. Several of these trioxanes have shown significant antimalarial activity again against multidrug resistant Plasmodium yoelii mice by the oral route. (C) 2004 Elsevier Ltd. All rights reserved.

Described herein is a palladium-catalyzed borylative cyclization and cyclopropanation of terminal alkyne-derived enynes, affording borylated bicycles, fused cycles, and bridged cycles in good isolated yields. The synthetic utility of this protocol was fully demonstrated by large scale reaction and synthetic derivatization of the borate group.
