S. Bouifraden et al., SYNTHESIS OF NEW GLYCOPEPTIDES FROM THE ALPHA-D-ALLOFURANOS-3-SPIROPROPIOLACTONE, Synthetic communications, 27(22), 1997, pp. 3909-3916
alpha-D-allofuranas-3-spiropropiolactone 3 was coupled with differents
amino esters in the presence of DMAP. This reaction lead to glycopept
ides with complete control of chirality.
