Abstract
The first and efficient total syntheses of (+/-)-triptoquinone B 1 and C2 have been achieved from the allyl ether3; the key steps are the co nstruction of the four contiguous stereogenic centres present in 2 by the Mn(III) mediated oxidative free radical cyclisation followed by me tal hydride reduction.
