produce ketones. Even in the presence of substrates and reagents with high steric hindrance, the organometallic compounds prepared from dry cerium(III) chloride and organomagnesium or organolithium compounds at -78 degrees C add cleanly to morpholine amides. The low cost of starting materials makes this new scheme of synthesis very interesting for the preparation of biologically important pheromones.
易于制备的吗啉酰胺与有机铈试剂以高收率结合,可制得酮。即使在存在高位阻的底物和试剂的情况下,由干氯化铈(III)和有机镁或有机锂化合物在-78摄氏度下制得的有机金属化合物也可以干净地添加到吗啉酰胺中。起始原料的低成本使得这种新的合成方案对于制备生物学上重要的信息素非常有趣。
