| abstract |
The invention relates to compounds of formula (I), in which R and R are independently a hydrogen atom, a (C1-C7) alkyl group, optionally substituted with one or more alkoxy groups; R is a (C1-C7) alkyl group; R represents a hydrogen atom, a (C1-C4) alkyl group; Y is a (C1-C4) alkoxy group, a group —NRR ′, —O (CH) —C (O) —NRR, where R and R ′ are as defined below, and n is an integer of 1 or 2 ; R ″ is a (C1-C4) alkyl group and R and R ′ are independently a hydrogen atom, a —CO— (C1-C4) alkyl group or a —COOR ″ group, where R ″ is as defined above.
