Addition of methanol to N-carboxy α-dehydroamino acid anhydride in the presence of NBS, followed by the treatment of the resulting product with base gave a new 2-oxazolinone-4-carboxylate.
在 NBS 存在下将甲醇加入 N-羧基 α-脱氢氨基酸酐,然后用碱处理所得产物,得到新的 2-恶唑啉酮-4-羧酸盐。

Syntheses of Heterocyclic Ethenyl <i>C</i>-Nucleosides for Recognition of Inverted Base Pairs within the DNA Triple Helix by Stereoselective Intramolecular Cyclization and Olefin Metathesis

within a triplex currently remains elusive. A series of C1-ethenyl nucleosides have been devised and evaluated extensively for stability and specificity by molecular dynamics simulation. A synthesis via olefin metathesis of the unprotected heterocycle and a conveniently prepared anomerically pure C1-vinyl 2-deoxyribofuranose is presented as a significant improvement over a previously reported strategy.
基因序列的规范识别将为特定的遗传干预提供精确的手段。不幸的是,目前仍然难以理解通过三链体形成寡核苷酸(TFO)将四个可能的碱基对中的两个特异性识别为X·TA和Y·CG。已经设计了一系列的C 1-乙烯基核苷,并通过分子动力学模拟对其稳定性和特异性进行了广泛的评估。提出了通过未保护的杂环的烯烃复分解和方便地制备的端基纯净的C 1-乙烯基2-脱氧核糖呋喃糖的合成,这是对先前报道的策略的重大改进。
