| abstract |
The present invention relates to new 2-aminomethyl-benzo [a] quinolizidine derivatives corresponding to the general formula I, (CF DRAWING IN BOPI) where: R1 represents either a hydrogen atom or a C1-4 alkyl group, linear , branched or cyclic, a hydroxy or C1-4 alkoxy group, branched, linear or cyclic, a halogen atom such as F or Cl, R2 represents a hydrogen atom or a C1-6 alkyl group, R3 represents a hydrogen atom or can constitute a unit (C=X) - NR4 R5 and then constitutes a urea or thiourea as with X=oxygen or sulphur, R4 and R5 can be independently a hydrogen atom or else an alkyl group in C1-8 linear, branched, cyclic, an aryl, aralkyl, aroyl group, these aryl groups possibly also being substituted, R4 and R5 can be linked by a carbon chain optionally incorporating a heteroactome. |
