P-CNAs are dinucleotide building blocks in which the torsional angles α and β of the sugar/phosphate backbone are constrained to non-canonical values within a cyclic phosphonate structure (phostone) synthesised by diastereoselective intramolecular Arbuzov reaction. The reaction has been improved through the use of microwave activation and addition of lithium bromide.
P-CNA 是二核苷酸结构单元,其中糖/磷酸盐骨架的扭转角 α 和 β 被限制为非对映选择性分子内 Arbuzov 反应合成的环状膦酸酯结构(膦)内的非规范值。通过使用微波活化和添加溴化锂,该反应得到了改进。
