Abstract
A series of new 1, 2-O-isopropylidene-3-O-methyl-6-deoxy-6-N, N-dialkylamino-α-D-glucofuranoses 1 and 1, 2-O-isopropylidene-3, 6-dideoxy-6-N, N-dialkylamino-α-D-glucofuranoses 1′ were prepared from α-D-glucose and their enantiose-lectivities compared as chiral catalysts for the ethylation of benzaldehyde and heptanal with diethylzinc.
