A new total synthesis of the antitumor alkaloids, pancratistatin (1), has been accomplished from readily available staring materials. The Claisen rearrangement of dihydropyranethylene 5 was employed to construct the A and C rings. Stereo- and regiocontrolled functional group interchange, such as iodolactonization, dihydroxylations, and a cyclic sulfate elimination reaction, allows for the production
