A one-pot Curtius rearrangement of dienyl carboxylic acids followed by a 6π-electrocyclization process to form substituted 2-pyridone products has been developed. Dienyl isocyanates generated from aliphatic acids were more reactive than their aromatic counterparts. Additionally, substitution patterns of the carboxylic acids had an impact on the efficiency of the cyclization.
This invention concerns novel dihydro- and tetrahydronaphthyridines useful for enhancing the lethal effects on tumor cells to treatment causing DNA-damaging activity as with ionizing radiation or with a chemotherapeutic agent.
