Reaction Conditions

Reaction Steps

Resorcinol (1 eq) was taken up in BF3.OEt2 (6 eq) and isobutyric acid (1 eq) added. The solution was heated for 1.5 hours at 90° C. than allowed to cool to room temperature. The solution was added drop wise to 10% NaOAc (aq) and allowed to stand for 4 hours, before being extracted in to EtOAc. The organic phases were combined and washed with sat. NaHCO3 (aq), then dried over magnesium sulfate, filtered and concentrated in vacuo to give 1-(2,4-dihydroxy-phenyl)-2-methyl-propan-1-one as a red oil which was used without additional purification
