PCT No. PCT/GB94/00396 Sec. 371 Date Mar. 14, 1995 Sec. 102(e) Date Mar. 14, 1995 PCT Filed Jul. 19, 1994 PCT Pub. No. WO95/03316 PCT Pub. Date Feb. 2, 1995Novel glycosides containing novel leaving groups, pyridyloxy, pyrimidyloxy, methoxypyridyloxy, pyridyl carbonate and pyridyl thiocarbonate are utilized in many fertile syntheses of glycosides, disaccharides, trisaccharides, oligosaccharides, nucleosides and the like. These synthetic schemes are superior in stereospecificity, yield and speed of preparation of numerous novel compounds. Polymer supported syntheses may be utilized within the general scheme to provided enhanced product purity. |
