  在二氯甲烷中用 N-乙酰基-5-N,4-O-羰基保护的硫唾液酸苷供体进行 O-唾液酸化：轻松选择性地裂解恶唑烷酮环

  摘要：

  制备了N-乙酰基-5- N , 4 - O-羰基保护的硫唾液酸苷供体，其结构已通过 X 射线晶体学确定，并在与各种受体的偶联中进行了测试。该供体在N-碘代琥珀酰亚胺和三氟甲磺酸原位活化方法（-40 °C 在二氯甲烷中）下与各种伯烷基和碳水化合物受体连接时具有优异的产率和 α-选择性。通过与N , N-二乙酰唾液酸供体的比较研究说明了恶唑烷酮子结构对 α-唾液酸化的有利影响，该供体表现出较差的产率和 α-选择性。唾液酸化选择性与供体的异头构型无关，但与NIS/TfOH活化方法下的反应温度高度相关。与 NIS/TfOH 方法相反，Ph 2 SO/Tf 2 O 促进在二氯甲烷中产生β-选择性偶联。N-乙酰基-5- N ,4- O-羰基保护的唾液酸苷（α-和β-端基异构体）的恶唑烷酮可以通过在温和条件下用甲醇钠处理而干净地裂解，而无需去除乙酰胺。

  摘要：

  The synthesis of a novel oxazolidinone sialosyl donor is reported. The introduction of a trans-fused ring enhances reactivity and stereoselectivity in glycosylation reactions for the synthesis of alpha-sialosides. The oxazolidinone ring can also be removed under basic conditions to afford the deprotected amine, which can be further functionalized. (c) 2006 Elsevier Ltd. All rights reserved.

  We describe efficient sialylation reactions in CH2Cl2 with the use of silylene/oxazolidinone double-locked sialic acid building blocks. The building blocks were synthesized from 4,5-oxazolidinone-protected phenylthiosialoside. In sialylation reactions towards primary and relatively reactive secondary hydroxy groups on the galactosides, the double-locked building blocks provided desired coupling products
