Abstract

The first successful preparation of mono-and disubstituted 3, 7-dihydroxytropolone involves a four-step synthetic scheme. Thus, bromination of 3, 7-dihydroxytropolone (8) followed by permethylation of the resultant products furnished gram quantities of intermediates 13-18. Single or double Suzuki coupling reactions between these permethylated monobromo-and dibromodihydroxytropolone derivatives and a variety of boronic acids delivered the ...
