title: Total synthesis of (-)-SNF4435 C and (+)-SNF4435 D.
abstract: [reaction: see text] A convergent, biomimetic total synthesis of the immunosuppressant polyketides SNF4435 C and D is described. The synthetic pathway features a stereo- and regioselective [3,3]-sigmatropic rearrangement as well as a high-yielding Stille coupling/8pi-6pi electrocyclization cascade.
