    摘要: The invention concerns compounds of formula (I) in which: R is —NO2 or —NHR3, R3 being hydrogen, —COR4 (R4 selected among (C1-C4) alkyl, aryl and aryl (C1-C4) alkyl, —COOR5 (R5 selected among (C1-C4) alkyl and aryl (C1-C4) alkyl), —CONHR6 or SO2R6 (R6 selected among (C1-C5) alkyl, aryl and aryl(C1-C4) alkyl), —SO2NR7R8 (R7 and R8 independently of each other represent hydrogen or (C1-C4) alkyl or form with the nitrogen atom a morpholine group), aryl (C1-C4) alkyl, R1 is a (C1-C4) alkyl group linear or branched, cyclo (C3-C8) alkyl, aryl optionally substituted, aryl (C1-C4) alkyl optionally substituted, heteroaryl, R2 is a hydrogen atom, a (C1-C4) alkyl or arylmethyl group, X is an oxygen or sulphur atom, a —CH2—, —SO2 or —NR1— group and Y is a hydrogen atom or (C1-C6) alkyl. The invention is applicable to synthesis intermediates.
