total enantioselective synthesis of (+)-(4S, 8R)-8-epi-β-bisabolol(+)-1 and of (−)-(4R, 8S)-4-epi-β-bisabolol ((−))−1) is reported. The key step in the synthesis is the kinetic resolution of (±)−5 by means of the Sharpless epoxidation yielding (−)- and (+}−6, respectively. Reduction of the epoxides with LiAlH4 gave the diols (+)-and(−)−7 which were transformed into (+)- and (−)−8, respectively, via
