摘要:以芳基溴和氯代叔丁烷为原料,经格氏反应得到相应叔丁基芳基酮。接着在四氯化钛、三乙胺存在下,与磺酰胺加成得到了10个新型的叔丁基芳基N-磺酰亚胺化合物,其结构经~1HNMR、^(13)CNMR、ESI-MS、IR和熔点等表征。并通过单晶X-射线衍射确定代表化合物的绝对构型为Z构型。该产物可以应用于生物活性物质的合成中。
The t-butyl ketones were prepared via Grignard reaction of aryl bromides and t-butylchloride.The corresponding ketones readily coupled in the presence of TiCl_4 and Et_3N with sulfamide.A series of t-butyl N-tosyl ketimines were obtained with good yields.The structures were confirmed by ^1HNMR,^13CNMR,ESI-MS,IR and melting point measurement.X-Ray crystal analysis showed that the products could be assigned with the Z configuration.The reduced products could subsequently be used in the synthesis of bioactive compounds.
