Jv. Allen et al., STEREOSELECTIVE EPOXIDATION OF ELECTRON-POOR DIENES USING POLY(L-LEUCINE), Journal of the Chemical Society. Perkin transactions. I, (22), 1997, pp. 3297-3298
Poly(L-leucine) catalysed oxidation of dienes 2, 3, 10, 16 and 18 and
the triene 17 furnishes the corresponding epoxides 4, 5, 11, 19, 21 an
d 20 respectively in good to excellent yield and in states of high opt
ical purity, Some regioselective reactions of the saturated epoxy keto
nes 5 and 11 are described.
