New triazine-type dehydrocondensing reagents, such as ROMP-Trz-Cl and ROMP(OH)-Trz-Cl, were synthesized by a ring opening metathesis polymerization (ROMP) method, and these showed higher loading than conventional polymer-supported condensing reagents. These polymers effect the formation of amides in good yields by addition of a mixture of carboxylic acid, amine and NMM. ROMP(OH)-Trz-Cl, which contains hydroxyl groups in the polymer chain, gave amides in good yields even in MeOH.
新型三嗪类脱缩合试剂,如ROMP-Trz-Cl和ROMP(OH)-Trz-Cl,采用开环复分解聚合(ROMP)方法合成,这些试剂的负载量高于传统的聚合物支持脱缩合试剂。这些聚合物通过加入羧酸、胺和NMM的混合物,能够以良好的产率形成酰胺。ROMP(OH)-Trz-Cl在聚合物链中含有羟基,即使在甲醇中也能以良好的产率生成酰胺。
