(S)-(+)-N-(2,3-Epoxypropyl)phthalimide → 2-((2R)-2-hydroxy-3-((4-(3-oxomorpholin-4-yl)phenyl)amino)propyl)-1H-isoindole-1,3(2H)-dione

Reaktionsschritte

In this case, 2-[(2S)-2-oxiranylmethyl]-1H-isoindole-1,3(2H)dione (II) is reacted with 4-(4-aminophenyl)-3-morpholinone (III) to give 2-((2R)-2-hydroxy-3-{[4-(3-oxo-4-morpholinyl)-phenyl]amino}propyl)-1H-isoindole-1,3(2H)dione (V). Subsequently, (V) is converted with a phosgene equivalent into 2-({(5S)-2-oxo-3-[4-(3-oxo-4-morpholinyl)phenyl]-1,3-oxazolidin-5-yl}-methyl)-1H-isoindole-1,3(2H)dione (VI). Elimination of the phthalimide protective group affords 4-{4-[(5S)-5-(aminomethyl)-2-oxo-1,3-oxazolidin-3-yl]phenyl}morpholine-3-one (VII) which is finally reacted with 5-chlorothiophene-2-carbonyl chloride (IV) to give 5-chloro-N-({(5S)-2-oxo-3-[4-(3-oxo-4-morpholinyl)phenyl]-1,3-oxazolidin-5-yl}methyl)-2-thiophenecarboxamide (I).
