✦ Synopsis


The first enantioselective synthesis of b-D and b-L N,O-psiconucleosides is reported. The synthetic approach is based on the asymmetric 1,3-dipolar cycloaddition of the C-[(4S)-2,2-dimethyl-1,3-dioxolan-4-yl]-N-methyl nitrone with ethyl 2-acetyloxyacrylate followed by Vorbru Β¨ggen nucleosidation, and removal of the chiral auxiliary. Stereochemical assignments are supported by a DFT theoretical study of the cycloaddition reaction.

The diastereo-and enantioselective synthesis of aand b-3%-hydroxymethyl-N,O-nucleosides is described, based on the 1,3-dipolar cycloaddition of a N-glycosyl nitrone. Two approaches have been evaluated: the one-step procedure, which uses vinyl nucleobases, showed a better stereoselectivity towards b-
