摘要:通过甲基丙烯酰氯和二甘醇胺反应设计合成了一种交联剂(2-甲基丙烯酰胺)乙氧基-2-甲基丙烯酸乙二醇单酯,以自行合成的(2-甲基丙烯酰胺)乙氧基-2-甲基丙烯酸乙二醇单酯为交联剂,丙烯酰胺为功能单体,合成了一种用于手性分离的N-叔丁氧羰酰-L-色氨酸(N-Boc-L-Trp,N-[(tert-butoxy)carbonyl]-tryptophan)的分子印迹聚合物。评价了该分子印迹聚合物作为高效液相色谱柱填料对N-叔丁氧羰酰-色氨酸(N-Boc-Trp)的手性拆分能力。结果表明:当检测波长为280 nm,流动相为V(甲醇)∶V(水)=80∶20,流速0.8 mL/min时,该填料实现了对N-Boc-Trp外消旋混合物的手性拆分,显示出良好的选择识别性能。
A new cross-linking monomer 2-(methacryloylamino)ethyoxyl -2-methacrylate ethandiol ester was designed, synthesized by methacryloyl chloride and 2-(2-aminoethoxy) ethanol. A kind of molecular imprinting polymers (MIPs) of N-[ (tert-buloxy) carbonyl ]-L-tryptophan (N-Boc-L-Trp) for chiral separation were synthesized using the 2-(methacryloylamino) ethyoxyl-2-methacrylate ethandiol ester as cross-linking monomer and acrylamide as function monomer. The chiral separation capability of this MIPs to N-BOC-tryptophan (N-Boc-Trp) was evaluated when it worked as a HPLC column filling. The experimental results showed that the chiral separation of N-Boc-Trp racemic mixture was performed by this MIPs and shown an excellent selective distinguish ability when detector wavelength is 280nm, mobile phase is methanol/water (80:20, v/v) and flow rate is 0.8 mL/min.
