Abstract
The compound 6-bromo-7-hydroxy-2,2,5-trimethylchroman-4-one (1) was desired for use in a project directed toward the synthesis of two novel depsidones. Since 7-hydroxy-2,2,5-trimethylchroman-4-one (2) was readily available, a number of bromination conditions were investigated in an attempt to find a regiospecific synthesis of 1. However, mixtures of varying composition of 1, 2, 3 and 4 were obtained under all the conditions tried. Final separation of 1 and its isomer 3 was accomplished by a mixture of chromatographic techniques. Structural assignment of the two brominated products 1 and 3 was made by a combination of carbon and proton NMR.
