applied to the traceless solid-phase organic synthesis of 1-substituted-4-vinyl-1,2,3-triazoles by CuI-promoted 1,3-dipolar cycloaddition reaction with various organic azides and subsequent cleavage from the polymer support through elimination reaction mediated by 1.8-diazabicyclo[5,4,0]undec-7-ene (DBU). The advantages of this new synthetic method include simple operation and moderate to good yields of
摘要 聚苯乙烯负载的丁-3-炔基磺酸酯试剂已被开发并应用于通过 CuI 促进的 1,3-偶极环加成无痕固相有机合成 1-取代-4-乙烯基-1,2,3-三唑与各种有机叠氮化物反应,随后通过由 1.8-二氮杂双环[5,4,0]十一碳-7-烯 (DBU) 介导的消除反应从聚合物载体上裂解。这种合成新方法的优点是操作简单,产品收率适中,试剂稳定性好。图形概要
