A cyclic fully N-protected hexameric (aminoethylglycinamide) can be readily obtained by using a divergent approach in liquid phase and consists of coupling orthogonal fragments of suitable oligomers. This cyclic N-protected backbone is then converted into a peptide nucleic acid by a series of selective deprotection–coupling steps affording the desired structure in good overall yields. Such a procedure
通过在液相中使用发散方法,可以容易地获得环状的完全被N-保护的六聚体(氨基乙基甘氨酰胺),并且其由偶联合适的低聚物的正交片段组成。然后,通过一系列选择性的脱保护-偶联步骤,将该环状的N-保护的主链转化为肽核酸,从而以良好的总收率提供所需的结构。这样的程序可以为靶向任何短环肽核酸(包含每种核碱基)提供一种通用方法。
