idehydroalanine methyl ester with diazoalkanes or ylides gives the corresponding cyclopropane derivatives in high yields. The cis/trans ratio of these compounds was dependent on substrate, reagent and reaction temperature. From stereochemically homogeneous compounds the corresponding 1-aminocyclopropanecarboxylic acids were easily obtained by acid hydrolysis.
N-(二苯基亚甲基)二氢化氢丙氨酸甲酯和N- [双(甲硫基亚甲基)二氢化氢丙氨酸甲酯与重氮烷烃或碘化物的反应以高收率得到相应的环丙烷衍生物。这些化合物的顺/反比取决于底物,试剂和反应温度。从立体化学均相化合物中,通过酸水解容易地获得相应的1-氨基环丙烷羧酸。
