Manganese(III)-mediated transformations of phloroglucinols: A formal oxidative [4 + 2] cycloaddition leading to bicyclo[2.2.2]octadiones

Article abstract of DOI:10.1021/ol900590t

Manganese(III)-mediated oxidative transformations of dearomatized phloroglucinol (1,3,5-trihydroxybenzene) derivatives are reported. A number of cyclization modes have been observed, including polycyclization to afford bicyclo[2.2.2]octadiones via a forma
