Intramolecular insertion of single enantiomers of cyclopropylidenes into 5,6-related CH bonds adjacent to nitrogen has been used to obtain enantiomerically pure methanoproline and a number of analogues with a high degree of one- or two-fold asymmetric induction.
已将环亚丙基的单个对映异构体分子内插入与氮相邻的5,6相关的CH键中,已获得对映体纯的甲氧脯氨酸和许多具有一或两倍不对称诱导高度的类似物。
