The catalytic asymmetric aminohydroxylation (AA) of 5-substituted-pent-2-enoates 8 and 17 was investigated as a route to 2,3,6-trideoxy-3-aminohexoses. The AA of ester 8, which bears a dimethyl acetal at C-5, favoured formation of the a-amino regioisomer 11 with optimum regioselectivity being observ
