我们介绍了所有的立体异构体的双氨基酸积木衍生自反式-4-羟基-1-脯氨酸。这个小的单体库允许在我们的螺梯低聚物内的任何手性中心处的任意立体化学构型。合成了三种含有单体1 - 4的多种组合的四聚体低聚物;我们通过核磁共振探讨了单体序列对支架构象的影响。
We introduce all stereoisomers of a bis-amino acid building block derived fromtrans-4-hydroxy-l-proline. This small library of monomers allows arbitrary stereochemical configuration at any chiral center within our spiro-ladder oligomers. Three tetramer oligomers containing several combinations of the monomers1−4were synthesized; we explored the effect of monomer sequence on scaffold conformation by NMR.
