T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety of alcohols. Alcohols are oxidized in situ to aldehydes under mild conditions, which undergo a three-component reaction with N,N'-dimethylbarbituric acid and various isocyanides to afford furo[2,3-d]pyrimidine-2,4(1H,3H)-diones in good yields.
