IDENTIFICATION OF THE 2-HYDROXYMETHYL-3,4-DIHYDROXYPYRROLIDINE (OR 1,4-DIDEOXY-1,4-IMINOPENTITOL) FROM ANGYLOCALYX BOUTIQUEANUS AND FROM ARACHNIODES STANDISHII AS THE (2R, 3R, 4S)-ISOMER BY THE SYNTHESIS OF ITS ENANTIOMER.

The D-xylo and L-arabino isomers of 1,4-dideoxy-1,4-iminopentitol have been synthesised from L-arabinose, and the L-arabino isomer was found to be the enantiomer of the alkaloid from Angylocalyx Boutiqueanus.The alkaloid from Arachniodes Standishii, recently reported to have the xylo configuration, was also shown to be the D-arabino isomer.
