Ester derivatives of 2-amino-2-phenyl-alkanol of general formula (I) in which: R
1
forms with R
3
and the nitrogen and carbon atoms to which they are respectively attached, a heterocycle with 4 to 7 members, optionally substituted in the α position of the nitrogen atom by one or two R
a
and R
b
radicals being able to be independently of one another hydrogen or linear or branched alkyl (1 to 4C), and R
2
is H or a —CO—O—CHR
4
—OCOR
5
radical for which R
4
is H or linear or branched alkyl (1 to 4C), and R
5
is alkyl optionally substituted by benzyloxycarbonylamino, acylamino or by the remainder of an amino acid, or represents a heterocycle, or R
2
is linear or branched alkyl (1 to 4C), alkyl (2 to 4C) substituted by OH, alkoxy, alkylthio, NH
2
, alkylamino, dialkylamino optionally forming with the nitrogen atom to which they are attached, a heterocycle with 5 or 6 members, it being understood that the substituted alkyl radical is linear or branched and comprises at least 2C between >N—R
2
and the substituent, unless specified otherwise, alkyl or acyl are linear or branched (1 to 7C), in their R or S forms or their mixtures, as well as its pharmaceutically acceptable salts, if any.
通用式(I)的2-氨基-2-苯基-醇的酯衍生物中:R1与R3及它们分别连接的氮和碳原子形成具有4至7个成员的杂环,该杂环可以在氮原子的α位被一个或两个Ra和Rb基团取代,这些基团可以独立地为氢或线性或支链烷基(1至4C),而R2为H或一个—CO—O—CHR4—OCOR5基团,其中R4为H或线性或支链烷基(1至4C),而R5为烷基,可以被苄氧羰基氨基、酰胺基或氨基酸的余部取代,或者代表一个杂环,或者R2为线性或支链烷基(1至4C),烷基(2至4C)被OH、烷氧基、烷基硫醚、NH2、烷基氨基、二烷基氨基取代,可能与它们连接的氮原子形成具有5或6个成员的杂环,其中被取代的烷基基团是线性或支链的,并且在>N—R2和取代基之间至少包含2C,除非另有规定,烷基或酰基是线性或支链(1至7C)的,以它们的R或S形式或它们的混合形式存在,以及它们的药用可接受盐,如果有的话。
