The present invention relates to derivatives of formula (I)
in which R1 and R2, identical or different, represent a hydrogen atom or a linear or branched C1-4 alkyl radical; provided that one of R1 and R2 is different from a hydrogen atom; R3 represents a bicyclic group of general formula (II):
X represents O or -CH2- or -(CH2)2-; in the form of a free base, of an hydrate or of a solvate.
本发明涉及公式(I)的衍
生物,其中R1和R2,相同或不同,代表氢原子或线性或支链C1-4烷基基团;前提是R1和R2中的一个不同于氢原子;R3代表一般式(II)的双环基团:X代表O或-
CH2-或-( )2-;以自由碱、
水合物或溶剂化合物的形式存在。
