This work deals with the synthesis of two mixed binary chiral selectors prepared by grafting (L)- or (D)-valine tert-butylamide on permethylated cyclodextrin macrocycle. The enantioselective properties of the new chiral selectors diluted in OV11 polysiloxane (35% phenyl- and 65% methylsiloxane) were investigated by means of injections of 117 racemic(More)
Two efficient routes are reported for the synthesis of both enantiomers of trifluoroalaninol in enantiopure form. The first pathway involves a Strecker-type reaction performed from a chiral trifluoromethyloxazolidine (Fox). The second route, which is more direct, involves, as a key step, the reduction of chiral oxazolidines or imines derived from ethyl(More)
Original mixed selectors were synthesized by coupling a single L-valine diamide moiety on permethylated β-cyclodextrin. The structures of the new selectors were designed to limit the interactions between the L-valine derivative and cyclodextrin by removing the amino acid moiety from the cyclodextrin cavity by means of an amide linkage on mono-6-amino(More)
