Proximity effects in the electron impact mass spectra of aurones and related compounds
摘要:
AbstractThe principal ions in the electron impact mass spectra of a series of 6‐methoxyaurones have been shown to be due to four separate reactions associated with proximity effects involving the phenyl group and the coumaran‐one residue. A detailed study with labelled derivatives has been supplemented by a study of the vinylogue 2‐cinnamylidene‐6‐methoxycoumaran‐3‐one and compounds in which the aurone phenyl group has been replaced by α‐naphthyl, β‐naphthyl and 9‐anthryl.
Compounds of Formula I, as shown below and defined herein: enriched in deuterium, and pharmaceutically acceptable salts thereof, synthesis, intermediates, formulations, and methods of disease treatment therewith, including cancers mediated at least in part by IGF-1R and/or IR.
