Jk. Karjalainen et al., AN IMPROVED HETEROGENEOUS ASYMMETRIC EPOXIDATION OF HOMOALLYLIC ALCOHOLS USING POLYMER-SUPPORTED TI(IV) CATALYSTS, Tetrahedron : asymmetry, 9(21), 1998, pp. 3895-3901
Heterogeneous asymmetric epoxidation of homoallylic alcohols has been
achieved using polymer-supported Ti(IV) catalysts with tert-butyl hydr
operoxide as oxidant. The enantioselectivities and chemical yields obt
ained are significantly higher tee values up to 80%) than with monomer
ic tartrate ligands. (C) 1998 Elsevier Science Ltd. All rights reserve
