Application of photoinduced acylnitrene aziridination to the syntheses of L-daunosamine and L-ristosamine glycosides is reported. Photoreaction of methyl 4-O-azidocarbonyl-2,3,6-trideoxy-L-hex-2-enopyranosides, followed by aziridine opening, leads to 3-am

Methyl and benzyl glycosides and glycal of L-acosamine (3-amino-2,3,6 trideoxy-L-arabino-hexose) have been stereoselectively prepared via 1,4-addition of hydrazoic acid to L-erythro-hex-2-enopyranose as a key step.Inversion of the C-4 configuration of met
SYNTHESIS OF (L)-DAUNOSAMINE AND RELATED AMINO SUGARS

1-(2-Furyl)ethanol (6) has been converted into methyl (+/-)-daunosaminide (1) and methyl (+/-)-ristosaminide (3) by use of an intramolecular cyclisation of a trichloroacetimidate group. (+/-)-Daunosamine (1) has been obtained more directly from the alcohol (10) by use of a modified Mitsunobu reaction; the scope of the latter reaction has been explored using cyclohex-2-en-1-ol as a model substrate.Asymmetric reduction of 2-acetylfuran (5) has given (S)-1-(2-furyl)ethanol (46) in good enantiomeric excess, thus providing a short route to the L-enantiomers of the amino sugars (1), (2), and (3) from a cheap, non-carbohydrate precursor.
Streptozotocin analogs

, (2008/06/13)
New 3-methyl-3-nitrosoureido derivatives of the following amino sugars were prepared as analogs of streptozotocin with the anomeric carbon protected, by nitrosating the methylureas in water with N2 O3 : 3-amino-3-deoxy-1,2-O-isopropylidene-α-D-ribofuranose; methyl 3-amino-3-deoxy-β-D-xylopyranoside; methyl 3-amino-3-deoxy-α-D-altropyranoside; methyl 3-amino-3-deoxy-α-D-glucopyranoside; and methyl 3-amino-2,3,6-trideoxy-α-L-lyxohexopyranoside. Tests against murine leukemia L1210 show that the anticancer activity of streptozotocin not only was retained but was enhanced in most of these derivatives.
