hydrolysis of 3,5-di- O -benzyl-1,2- O -cyclohexylidene-α- d -xylofuranose gave the corresponding lactol, which was subsequently converted to the 3,5-di- O -benzyl-2- O -mesyl- d -xylofuranose. This compound readily reacted with sodium methoxide, sodium benzylate or sodium hydroxide (presumably via the corresponding 1,2-anhydride) to give the protected d -lyxofuranosides. These compounds were finally
摘要对3,5-二-O-苄基-1,2-O-环己叉基-α-d-木呋喃糖进行酸水解得到相应的内酯,随后将其转化为3,5-二-O-苄基-2- O-甲磺酰基-d-木呋喃糖。该化合物容易与甲醇钠,苄基钠或氢氧化钠反应(大概通过相应的1,2-酐),得到保护的d-呋喃呋喃糖苷。这些化合物最终被转化为甲基α-d-lyxopyranoside或d-lyxose。
