稳定的同位素标记的N-酰基硒酮已被构建在不到四个步骤,从容易获得的起始材料。位点特异性标记是使用以下双离子实现的:溴[2- 13 C]乙酸、[13 C]甲酸和元素77 Se。已发现这些标记的selones提供了独特的见解烯醇化物的结构,并可能是有用的,在检测和定量的远程配置的手性中心的化合物供应短缺。
Stable isotope-labeledN-acyl selones have been constructed in fewer than four steps from readily available starting materials. Site-specific labeling was achieved using the following synthons:  bromo[2-13C]acetic acid, [13C]formic acid, and elemental77Se. These labeled selones have been found to provide unique insights into enolate structure and may be useful in the detection and quantitation of remotely disposed chiral centers in compounds in short supply.
