Concise synthesis of the chemopreventitive agent (+/-)-deguelin via a key 6-endo hydroarylation.
[reaction: see text]. A concise total synthesis of (+/-)-deguelin was achieved with a longest linear sequence of six steps in 68% yield. A key step was the platinum-catalyzed 6-endo hydroarylation of an alkynone intermediate.
