Abstract
Condensations of 1,4-bis(4-aminophenoxy)butane Ia and its N,N'-dimethyl derivative Ib with substituted diethyl malonates gave 1,4-bis(4-hydroxy-2-oxo-1,2-dihydroquinolin-6-yloxy)butanes IIa-IIf. From these compounds, 1,4-bis(3-halogeno-2,4-dioxo-1,2,3,4-tetrahydroquinolin-6-ylox y)butanes IIIa-IIIg and 1,4-bis(3-hydroxy-2,4-dioxo-1,2,3,4-tetrahydroquinolin-6-yloxy )butanes IIIh-IIIm were prepared.
