A. Klasek et al., SYNTHESIS AND SOME REACTIONS OF 3-SUBSTITUTED -HYDROXY-2-OXO-1,2-DIHYDROQUINOLIN-6-YLOXY)BUTANES, Collection of Czechoslovak Chemical Communications, 60(12), 1995, pp. 2137-2146
Condensations of 1,4-bis(4-aminophenoxy)butane Ia and its N,N'-dimethy
l derivative Ib with substituted diethyl malonates gave -hydroxy-2-oxo
-1,2-dihydroquinolin-6-yloxy)butanes IIa-IIf. From these compounds, 4-
dioxo-1,2,3,4-tetrahydroquinolin-6-yloxy)butanes IIIa-IIIg and 4-dioxo
-1,2,3,4-tetrahydroquinolin-6-yloxy)butanes IIIh-IIIm were prepared.
