demonstrated that the polymers, poly(1)−poly(3), have stereoregular structures (cis = 100%) and equally populated right- and left-handed helical conformation. A predominant helix sense was induced in these polymers by the addition of chiral alcohols or amine, which was confirmed by CD and UV−vis spectroscopies. 1H NMR and CD spectroscopic studies strongly suggested that the poly(N-propargylamides) interacted
非手性N-炔丙基酰胺,即N-炔丙基-3-甲基丁酰胺(1),N-炔丙基-2-乙基丁酰胺(2)和N-炔丙基-3,3-二甲基丁酰胺(3)与(nbd)Rh聚合+ [η 6 -C 6 H ^ 5 B-(C 6 H ^ 5)3 ],得到具有中等分子量(聚合物中号ñ以良好产率= 6000-22 000)。的1 H NMR和UV-vis光谱表明,聚合物,聚(1) -聚(3),具有立体规则的结构(顺式= 100%),并且右手和左手螺旋构型均相同。在这些聚合物中,主要的螺旋感是通过添加手性醇或胺来诱导的,这可以通过CD和UV-vis光谱学得到证实。1 H NMR和CD光谱学研究强烈表明,聚(N-炔丙基酰胺)通过在聚合物侧链的酰胺基上的氢键与手性醇相互作用。手性萜烯也可以诱导单手螺旋构象。这可能是疏水相互作用导致了单手螺旋构象的手性萜烯的情况下,因为加的ñ正己烷降低CD信号。
