  Hydrothermal Deamidation of 4-N-Acylcytosine Nucleoside Derivatives:  Efficient Synthesis of Uracil Nucleoside Esters

  摘要：

  [GRAPHICS]N,O-Peracylated cytidine and 2'-deoxycytidine derivatives in superheated water/DME solutions (oil bath at 125 degrees C) undergo hydrolytic deamidation (and/or N-deacylation). Acylated starting materials derived from arylcarboxylic acids give the corresponding uridine esters cleanly, and such derivatives crystallize selectively from the cooled reaction mixtures in high yields.

  A simple treatment of fully aroylated purine and pyrimidine ribo-nucleosides with pulverized potassium tert-butoxide in tetrahydrofuran (THF) or dichloromethane under a controlled condition gave a mixture of the corresponding di-O-aroyl derivatives in which 2'-OH derivatives are preponderant over 3'-OH derivatives; 3',5'-di-O-benzoyluridine, N4, 3', 5'-tribenzoylcytidine, N4, 3', 5'-tri-o-toluoylcytidine

  Strategically derivatized NPOE glycosyl donors, are able to efficiently glycosylate silylated nucleobases under mild conditions, even as low as −78 °C if necessary. Ensuring trans-1,2 glycosylation, thus permitting, unlike classical procedures, a Reverse Strategy for the synthesis of ribonucleosides, where glycosylation occurs late, rather than early, and convergency is optimized.

  战略性衍生化的NPOE糖苷供体能够在温和条件下高效地糖苷化硅烷化的核苷碱碱基，必要时甚至可以低至−78°C。这确保了反式-1,2糖苷化，从而与传统方法不同，允许采用反向策略合成核糖核苷，在这种策略中，糖苷化发生得较晚，而不是较早，并且优化了收敛性。

  A treatment of fully acylated purine and pyrimidine ribonucleosides with a small excess amount of sodium methoxide in THF at room temperature gave the corresponding 5'-acylates in excellent yields; N-acyl groups on the nucleic acid base moieties of adenosine and cytidine in addition to guanosine derivatives satisfactorily survived under the conditions used.

  在室温下用少量过量的甲醇钠在THF中处理完全酰化的嘌呤和嘧啶核糖核苷，得到的相应5'-酰化物收率很好；除鸟苷衍生物外，腺苷和胞苷的核酸碱基部分上的N-酰基在所使用的条件下令人满意地存活。

  A protocol for chemoselective deprotection of N,O-acylated ribonucleosides has been developed. Peracylated pyrimidine ribonucleosides subjected to guanidinium nitrate and NaOMe in MeOH/CH2Cl2 at 0 °C undergo high yielding O-deacylation, while even more pronounced chemoselectivity is observed with peracylated purine ribonucleosides as O5′-acyl groups are preserved. Nucleobase-protecting groups (ABz

  已经开发出用于N，O-酰化核糖核苷的化学选择性脱保护的方案。在0°C下于MeOH / CH 2 Cl 2中于硝酸胍和NaOMe中进行过酰化的嘧啶核糖核苷进行高产率的O-脱酰化，而由于保留了O5'-酰基，因此在过酰化的嘌呤核糖核苷中观察到的化学选择性更高。核碱基保护基团（A Bz，C Bz，G iBu和U Bz）在这些条件下稳定，使该试剂混合物成为收集核苷化学中保护基方案的宝贵补充。
