A new approach to the tandem synthesis of 2,4-disubstituted or 2,4,6-trisubstituted pyrimidines from propargylic alcohols with amidine is described. This reaction is catalyzed by 20 mol% Cu(OTf)(2) to give pyrimidines in moderate to good yields via a propargylation-cyclization-oxidation tandem sequence.
