Cyclopropanation of α,β-unsaturated N-methoxy-N-methyl amides provided the cyclopropyl amides in far superior yields to those obtained with the corresponding ketones. The desired ketones are then readily accessible by the addition of organometallic reagents. Access to a variety functional groups, including aldehydes and carboxylic acids, is also described.
α,β-不饱和N-甲氧基-N-甲基酰胺的环丙烷化提供的环丙基酰胺的收率远高于用相应的酮获得的收率。然后通过添加有机金属试剂可以容易地获得所需的酮。还描述了对包括醛和羧酸在内的各种官能团的获取。
