Structural elucidation of an oxidation product of sedimentary porphyrins by one-pot synthesis of 3-methylphthalimide

10.1246/bcsj.74.1975

Shinya Nomoto et al. report the development of a one-pot synthesis method for 3-methylphthalimide starting from 1,2,3-trimethylbenzene. The process involves multiple steps, including bromination, nitric acid oxidation, conversion to an anhydride, and a thermal reaction with urea. The synthesized 3-methylphthalimide was confirmed to be identical to an oxidation product of sedimentary porphyrins previously identified by Barwise and Whitehead. Sedimentary porphyrins, which are complex mixtures resulting from the diagenetic modification of chlorophylls, have substitution patterns that can be determined after decomposition to maleimides. The study's findings provide a practical method for synthesizing 3-methylphthalimide, which is not commercially available, and offer insights into the precursors of benzoporphyrins in geological samples.
