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.

Regioselective Monoacylation of Some Glycopyranosides via Cyclic Tin Intermediates

Selective mono-benzoylation of some pento- and hexo-pyranosides (Me β-L-Ara, Ph α-L-Ara, Me α-D-Xyl, Me β-D-Xyl, Me α-D-Glc, Me-β-D-Glc, Me α-D-Gal, Me β-D-Gal, and Me α-D-Man) by using Bu2SnO was examined in comparaison with the results of the (Bu3Sn)2O method and direct benzoylation.The Bu2SnO method is particularly useful in that it selectively activates an equatorial hydroxyl group wich bears an oxygenated function (OH or OMe) in a cis relationship at an adjacent position, even in the presence of a more reactive primary OH group.The various mono- and di-O-benzoyl derivatives prepared in this work were unambiguously identified by analysis of their 13C-nuclear magnetic resonance spectra.

REGIOSELECTIVE O-DEACYLATION OF FULLY ACYLATED GLYCOSIDES AND 1,2-O-ISOPORPYLIDENEALDOFURANOSE DERIVATIVES WITH HYDRAZINE HYDRATE

On hydrazinolyis in 1:4 acetic acid-pyridine, and in pyridine, partisl O-deacylation of fully acylated methyl glycosides and some other glycosyl compounds ( 23 compounds ) was found to be induced, to give, in good yields, products bearing one free hydroxy
