Synthesis and Nuclear Magnetic Resonance Studies of Some N-Acylated Methyl 4-Amino-4,6-dideoxy-alpha-D-mannopyranosides

The methyl alpha-glycosides of 4-amino-4,6-dideoxy-D-mannopyranose (perosamine), N-acylated with either formic, acetic, or (S)-2,4-dihydroxybutanoic acid, have been synthesized.The (1)H and (13)C n.m.r. spectra of these substances and the parent, non-N-acylated glycoside, demonstrated how the chemical shifts are influenced by the N-acylation.The N-formyl derivative occured in two conformations, s-cis and s-trans, and the free-energy barrier between these, 86.9 kJ mol-1, was defined by dynamic n.m.r. spectroscopy.

Enantioselective synthesis of alpha-hydroxy gamma-butyrolactones from an ephedrine-derived morpholine-dione

An ephedrine-derived morpholine dione is employed in the enantioselective synthesis of (S)-alpha-hydroxy gamma,gamma-dimethyl-gamma-butyrolactone and (S)-alpha-hydroxy gamma-butyrolactone. A one-pot alkylation/allylation protocol for the stereoselective conversion of the dione to 2-alkyl-2-allyl morpholinones, key intermediates for alpha-alkyl-alpha-hydroxy-gamma-butyrolactones, is described.

Synthesis of 1alpha,25-dihydroxy-24R-fluorocholecalciferol and 1alpha,25-dihydroxy-24S-fluorocholecalciferol

1alpha,25-Dihydroxy-24R-fluorocholecalciferol and 1alpha,25-dihydroxy-24S-fluorocholecalciferol, analogs of 1alpha,25-dihydroxy-cholecalciferol which is physiologically the most active metabolite of vitamin D3, are synthesized in a multistep process from the known substance 1alpha,3beta-dihydroxyandrost-5-en-17-one. The new analogs are characterized by the ability to increase intestinal calcium transport, increase serum calcium and phosphate concentrations and to increase the deposition of these minerals in bones. These compounds will find a ready application as substitutes for natural 1alpha,25-dihydroxycholecalciferol in the treatment of disease states characterized by metabolic calcium and phosphate deficiencies. Exemplary of such disease states are the following: osteosclerosis, anticonvulsant treatment, osteopenia, fibrogenesis-imperfecta ossium, secondary hyperparathyrodism, hypoparathyroidism, hyperparathyroidism, cirrhosis, obstructive jaundice, drug induced metabolism, medullary carcinoma, chronic renal disease, hypophosphatemic VDRR, vitamin D-dependent rickets, sarcoidosis, glucocorticoid antagonism, malabsorption syndrome, steatorrhea, tropical sprue, idiopathic hypercalcemia and milk fever.
