Various alkoxy-substituted heterocyclic stannanes provide access to the corresponding substituted 'pyridone' moieties via Stille cross-coupling. Both pyridyl and a series of diazinyl stannanes are prepared, and options for unmasking (via demethylation or debenzylation) of the pyridone unit are evaluated. Georg Thieme Verlag Stuttgart.

We herein report that flash heating microwave irradiation is a helpful tool in the formation of arylpyrimidines from the corresponding halopyrimidines. The palladium-catalyzed cross-coupling reactions of 2,4-di- and 2,4,5-trihalopyrimidines with phenylboronic acid under the above conditions are described. By use of the appropriate catalyst and the adequate halopyrimidine, good regioselectivity can be achieved in the 2-, 4-, or 5-positions of the heterocycle. In addition, we show that this methodology is ameneable for the stepwise preparation of mono-, di-, and triphenylpyrimidines.
