摘要
以芳香醛为原料,经安息香缩合反应合成了5个2-羟基-1,2-二芳基乙酮类物质,并对该反应条件进行了优化,得到了最佳合成条件为:20 mol%催化剂,10 mol%NaOH,V(H2O)∶V(C2H5OH)=1∶3。2-羟基-1,2-二芳基乙酮类物质经氯代、环合最终合成2-氨基噻唑衍生物。产物结构经IR、1HNMR和HRMS进行表征。
Five 2-hydroxy-1,2-diarylenthanones were synthesized by benzoin condensation with aromatic aldehydes as raw material and the reaction conditions were investigated. The optimized conditions are :n(catalyst) = 20 mol% ,n(NaOH) = 10 mol% ,and V(H2O) : V(C2H5OH) = 1 : 3 as reagent. The 2- amino-4,5-diarylthiazoles were synthesized from 2-hydroxy- 1 ,2-diarylenthanones by a two-step reaction of chlorination and cyclization. The structures of were confirmed by IR, ^1HNMR and HRMS.
