Utilisation d'ylides du phosphore en chimie des sucres. XII Dérivés du D-arabino-hexène-1-tétrol-3,4,5,6

The preparation of several kinds of derivatives of 1-substituted D -arabinc-hex-1-ene-3,4,5,6-tetrols is described. Some of these compounds, having a ‘pseudo-formyl’ group (? CH?CHCN, ? CH?CHSO₂CH₃) are ‘pseudo-aldehydo-sugars’. Their ability to react as aldehydo-sugars was examined in light of their ¹³C-NMR. spectra which provide information on their electron density at C(1) and C(2).
