A. Mauvais et E. Winterfeldt, DIENES AS CHIRAL TEMPLATES - EASY ACCESS TO PURE (2S,3S,4R)-4-HYDROXY-2,3-EPOXYCYCLOHEX-5-EN-1-ONE, Tetrahedron, 49(26), 1993, pp. 5817-5822
The title compound 6 was obtained stereospecifically through a concise
sequence including a Diels-Alder reaction with the chiral diene 2 and
the retro reaction. The Favorskii rearrangement starting from the int
ermediate epoxide 4 was found to be regioselective.
