The invention relates to compounds of formula (I):
wherein R
1
and R
2
together form the following carbon-containing chain:
wherein:
R
3
represents a hydrogen atom or an alkyl group,
R
4
represents a hydrogen atom or an alkyl, aryl, heteroaryl, 3,4-dioxocyclobutenyl, alkylcarbonyl, cycloalkylcarbonyl, heterocycloalkylcarbonyl, benzoyl, arylsulphonyl or heteroarylsulphonyl group, each of those groups optionally being substituted,
or R
3
and R
4
together with the nitrogen atom carrying them form a 5- to 8-membered ring, the ring thereby formed optionally being substituted.
Medicinal products containing the same which are useful in treating conditions requiring a D3 receptor antagonist.
该发明涉及以下式(I)的化合物:
其中R1和R2共同形成以下含碳链:
其中:
R3代表氢原子或烷基基团,
R4代表氢原子或烷基、芳基、杂芳基、3,4-二氧代环丁烯基、烷基羰基、环烷基羰基、杂环烷基羰基、苯甲酰基、芳基磺酰基或杂芳基磺酰基基团,其中每个基团可选择地被取代,
