M. Kodama et al., TOTAL SYNTHESES OF BOTH ENANTIOMERS OF SARCOPHYTOL-A AND SARCOPHYTOL-T BASED ON STEREOSPECIFIC [2,3]WITTIG REARRANGEMENT, Tetrahedron letters, 34(52), 1993, pp. 8453-8456
Both enantiomers of sarcophytols A (1) and T (2), cembranolide diterpe
nes isolated from a soft coral, were synthesized from a common chiral
intermediate, obtained by baker's yeast reduction, using a stereospeci
fic [2,3]Wittig rearrangement as the key step.
