1. Cyclic imides IV. The reaction of some N-substituted nitrophthalimides with sodium methoxide
2. A Study of the Aminophthalimidoacetic Acids1
3. Melting points were determined with an Electrothermal melting point apparatus and are not corrected. Microanalyses were done by Atlantic Microlab, Inc., Atlanta, Georgia, or by PCR, Inc., Gainesville, Florida. Uv absorption spectra were determined with a Gary 15 spectrophotometer, ir absorption spectra with a a Perkin-Elmer 225 grating spectrophotometer, and nuclear magnetic resonance spectra with a Varian A-60A nmr spectrometer.
