The invention concerns compounds of general formula (1) wherein R
1
represents H, alkyl,cycloalkyl or cycloalkylalkyl and R
2
represents H or alkyl; R
3
represents H, alkyl or aralkyl; X represents a bond or a linear or branched alkylene radical (II); Y represents H, cycloalkyl, OR
14
, SR
15
, NR
4
R
5
or A represents a bond or phenyl; B and B′ are independently selected among alkyl, NR
6
R
7
, SR
8
and carbocyclic aryl orheterocyclic aryl radicals with five or six members optionally substituted; R
4
represents H, alkyl, aryl, cycloalkyl, cycloalkylalkyl, aralkyl, C(O)R
9
, C(O)OR
9
, —C(O)NHR

or —SO
2
R
9
, or further aryl or aralkyl whereof the aromatic ring is optionally substituted and R
5
represents in particular H or alkyl, or further R, and R
5
form with the nitrogen atom bearing them a non-aromatic hetcrocycle of five to seven members optionally substituted; R
6
represents (in particular) II or alkyl and R
7
represents (in particular) II or alkyl; R
8
represents an alkyl radical optionally substituted; R
