Well-controlled and extremely rapid ring-opening metathesis polymerization of unusual oxanorbornene lactam esters by Grubbs third-generation catalyst is used to prepare a range of bio-based homo- and copolymers. Bio-derived oxanorbornene lactam monomers were prepared at room temperature from maleic anhydride and secondary furfuryl amines by using a 100 % atom economical, tandem Diels-Alder lactamization reaction, followed by esterification. Several of the resulting homo- and copolymers show good control over polymer molecular weight and have narrow molecular weight distributions.
利用格拉布第三代催化剂对特殊的氧杂降冰片烯内酰胺酯进行可控且极其快速的开环易位聚合反应，以制备一系列生物基均聚物和共聚物。通过100%原子经济的串联狄尔斯-阿尔德内酰胺化反应，由马来酸酐和仲糠胺在室温下制备生物衍生的氧杂降冰片烯内酰胺单体，随后进行酯化反应。所得的几种均聚物和共聚物对聚合物分子量具有良好的控制，且分子量分布较窄。
