Amino and diamino acid derivatives having the formula:
where: R can be NH2- or A-O-C,
A being hydrogen, an alkaline metal, an amino or ammonic radical or an aliphatic radical;
n is a whole number between 2 and 5;
X is hydrogen or a lower alkyl radical with 1-4 carbon atoms;
R1 is hydrogen, an alkaline metal, an amino or ammonic, radical or an aliphatic radical;
can be prepared by condensing diamines or omega-amino acids, or their lactams or aliphatic esters, with alpha-halogenated lower aliphatic acids or with their aliphatic esters, with possible subsequent salification with alkaline hydrates or with amino or ammonic compounds or with esterification with aliphatic alcohols.
Such compounds are used as plant growth stimulants or as pharmaceutical products.

其中R 可以是 NH2- 或 A-O-C、
A 可以是氢、碱金属、氨基或氨自由基或脂肪族自由基;
n 是介于 2 和 5 之间的整数;
X 是氢或含 1-4 个碳原子的低级烷基;
R1 是氢、碱金属、氨基或氨自由基或脂肪族自由基;
可通过二元胺或欧米伽氨基酸或其内酰胺或脂肪族酯与α-卤化低级脂肪族酸或其脂肪族酯缩合制备,随后可与碱性水合物或氨基或氨化合物盐化,或与脂肪族醇酯化。
此类化合物可用作植物生长刺激剂或医药产品。
