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
Aldose reductase inhibitors of the formula ##STR1## in which R.sup.1 is COOH and R.sup.2 is hydrogen, 8-halo or 6-hydroxy, or R.sup.1 is CON(R.sup.3)-CH.sub.2 COOH wherein R.sup.3 is lower alkyl and R.sup.2 is hydrogen or 8-halo are useful for treating diabetic complications.
