## Abstract The two isomeric monocarbamates, 2b and 2c, related to the antitumor drug carmethizole (1) were synthesized and the structure of the carmethizole hydrolysis product, 2b, was established by Xβray crystallography. The chemical reactivity, toxicity, and antitumor activity of the two monoca

## Abstract The structure of an unexpected compound from the dehydration of an aldol addition product has been determined using 1βD and 2βD NMR techniques. This reaction is the last step in a new synthetic approach to the galanthan ring system. Complete ^1^H and ^13^C NMR assignments for two synthe
## Abstract The compound mentioned in the title is shown by Xβray analysis to be 1, 2, 7, 8βtetraazaβ4, 5, 10, 11βtetraoxatricyclo [6.4.1.1^2, 7^] tetradecane, contrary to previous suggestions. The torsion angle about the peroxo bonds in the sevenβmembered rings in 100Β°, close to the value in hydro
Glycosylphosphatidylinositol (GPI) membrane anchors are synthesized in the endoplasmic reticulum of eukaryotic cells. Synthesis of the core GPI structure is achieved by the sequential transfer of monosaccharides and phosphoethanolamine to phosphatidylinositol. The assembly process can be reproduced
