Ql. Meng et al., Novel thiazolidine derivatives as chiral catalysts in the enantioselectiveaddition of diethylzinc to aldehydes, TETRAHEDR-A, 11(21), 2000, pp. 4255-4261
New chiral thiazolidine derivatives were synthesized conveniently from natu
ral L-cysteine and showed good enantioselectivity (up to 90% ee) in the add
ition of diethylzinc to aldehydes. The catalytic efficiency of the thiazoli
dine derivatives is influenced by the different structures of the thiazolid
ine rings and the bulkiness of R moiety in the ester groups. (C) 2000 Elsev
