Novel N-substituted-aminomethyl cyclopropyl ketone derivatives are represented by following Formula (1):
1
wherein R
1
, R
2
and R
3
are each a hydrogen atom or an aliphatic hydrocarbon group; and R
4
and R
5
are each a hydrogen atom or an arylmethyl group which may have a substituent, where at least one hydrogen atom or aryl group as a substituent is combined with a carbon atom in the methyl moiety of the arylmethyl group, and at least one of R
4
and R
5
is an arylmethyl group which may have a substituent. These compounds are useful for the preparation of aminomethyl cyclopropyl ketone derivatives and 2-amino-1-cyclopropylethanol derivatives or salts thereof.
新型N-取代氨甲基环丙基酮衍生物由以下式(1)表示:其中R1、R2和R3分别是氢原子或脂肪烃基;R4和R5分别是氢原子或苄基基团,可能具有取代基,其中至少有一个氢原子或苄基作为取代基与苄基基团的甲基部分中的碳原子结合,且R4和R5中至少一个是可能具有取代基的苄基基团。这些化合物适用于制备氨甲基环丙基酮衍生物和2-氨基-1-环丙基乙醇衍生物或其盐。
