66. Thermal Reactions of 2-(2-Oxo-3-nitro-4-quinolinyl)-malonates
Täubl A.E., Stadlbauer W., J. Heterocycl. Chem.,34 (1997), 989-991

Abstract: Depending on the ester substituent, diethyl 2-(3-nitro-2-oxo-4- quinolinyl)-malonates give upon thermolysis ethyl 2-(3-nitro-2- oxo-4-quinolinyl)-acetates, whereas dimethyl 2-(3-nitro-2-oxo- 4-quinolinyl)-malonates cyclize to give 1-methoxycarbonyl- isoxazolo[3,4-c]quinolin-4(5H)-ones. The necessary reaction conditions can be obtained easily with the help of DSC.
