CATALYTIC ENANTIOSELECTIVE REACTIONS .7. SYNTHESIS OF NEW BETA-AMINOALCOHOLS DERIVED FROM ALPHA-D-GLUCOSE AS CHIRAL CATALYSTS FOR THE CATALYTIC ENANTIOSELECTIVE ADDITION OF DIETHYLZINC TO ALDEHYDES

摘要

A series of new 1,2-O-isopropylidene-3-O-methyl-6-deoxy-6-N,N-dialkylamino-alpha-D-glucofu ranoses 1 and 1,2-O-isopropylidene-3,6-dideoxy-6-N,N-dialkylamino-alpha-D-glucofuranoses 1' were prepared from alpha-D-glucose and their enantioselectivities compared as chiral catalysts for the ethylation of benzaldehyde and heptanal with diethylzinc.
