Synthesis of enantiomerically pure hydroxylated pyrroline N-oxides from d-ribose

A convenient way to obtain enantiomerically pure hydroxylated pyrroline N-oxides is reported. The key step is the formation of ω-oxo enoates from d-ribose and a subsequent 1,3-azaprotio cyclotransfer reaction of the resulting oximino alkenoate derivatives

STEREOSELECTIVITY IN THE FORMATION OF UNSATURATED WITTIG PRODUCTS AND STEREOSPECIFICITY IN THEIR ELECTROPHILE INDUCED CYCLIZATION TO C-GLYCOSIDES.

The stereoselective synthesis of E and Z unsaturated Wittig products derivated from 2,3-O-isopropylidene-5-O-trityl-D-ribofuranose (3) and 2,3:5,6-di-O-isopropylidene-D-mannofuranose (4) was described, as well as their stereospecific cyclization induced b
