Title:
GEMINALLY SUBSTITUTED AMINES
Document Type and Number:
WIPO Patent Application WO1999065318
Kind Code:
A3
Abstract:
The present invention relates to an amine of general formula (I), in which R<1> and R<2> may be the same or different and represent each independently substituted or non-substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkinyl, aryl or trialkylsilyl. R<1> and R<2> can also form together with the nitrogen atom to which they are bound a substituted or non-substituted cycloalkyl ring which may contain, together with the nitrogen atom, at least one other heteroatom selected from the group comprising nitrogen, oxygen and sulphur. R<3> is selected from the group comprising hydrogen and methyl optionally substituted with 1 to 3 fluorine atoms, while R<4> and R<5> may be the same or different and represent each independently substituted or non-substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl or alkinyl. This invention also relates to a salt thereof.
