PROCESS FOR PREPARING 2,3-DIAMINOPROPANOLS AND SYNTHESIS OF OTHER COMPOUNDS USING 2,3-DIAMINOPROPANOLS

摘要

The invention relates to a process for producing 2,3-diaminopropanol of formula (II) from aziridine of formula (I) wherein, R<1> is selected from a group consisting of hydrogen, alkyl, cycloalkyl, acyl, aryl, hydrocarbon residues, aralkyl, and those groups substituted with suitable substituent(s); R<2> is selected from a group consisting of hydrogen, alkyl, cycloalkyl, C2-C5-alkenyl, aralkyl which may be optionally substituted with suitable substituent(s), aryl which may be optionally substituted with suitable substituent(s), and heteroaryl which may be optionally substituted with suitable substituent(s); each of R<3> and R<4> is independently selected from a group consisting of hydrogen, C1-C12 alkyl, C1-C12 alkylcarbonyl, C1-C12 alkyloxycarbonyl, aryl, mono- or di(C1-C12)alkylamino, mono- or di(C1-C12)amino carbonyl, wherein C1-C12 may be optionally substituted, or R<3> and R<4>, together with nitrogen atom which they are attached to, may form pyrrolidinyl, piperidinyl, morpholinyl, azido or mono- or di(C1-C12)alkylamino C1-C4 alkylidene.
