Synthesis of ethers of (+)-usninic acid pyrazole derivatives

The reduction of usninic acid pyrazole derivatives by complex boron hydrides under various conditions was studied. New ether derivatives containing added alcohols were obtained upon reduction of the carbonyl. The reaction occurred presumably through a quinonemethide intermediate.
