  • Intermediates for use in retinoid synthesis
    Patent number: 7323589
    Abstract: The invention concerns compounds of formula (1) wherein in particular G represents the —N(CH3)2—, —N(C2H5)2-group or N-pyrrolidine: n is an integer equal to 1 or 2: R1, R2 and R3, independently of one another, represent a hydrogen atom or a methyl group, the successive unsaturated units capable of being moreover identical or different, provided that at least one of the substituents R1, R2 and R3 is different from H: and Y1 and Y2 represent each a —COOCH3 group or a COOC2H5 group.
    Type: Grant
    Filed: December 27, 2005
    Date of Patent: January 29, 2008
    Assignee: Centre National de la Recherche Scientifique (CNRS)
