The tetrahydrofuran portion 3 of verrucosidin 1, a potent neurotoxin, is synthesized in an enantiomerically pure form via the stereoselective osmylation of the chiral hydroxy diene ester 5 as a key step.

The emeriones, three highly oxidized and densely functionalized polyketides, were synthesized from two enantioenriched fragments in a Stille-8π/6π sequence, followed by late-stage stereo- and chemoselective oxidations. This work enabled the structural revision of emerione C.
