Ec. Taylor et al., 6-TRIFLUOROMETHANESULFONYLOXY-4(3H)-PYRIMIDINONES AS VERSATILE INTERMEDIATES FOR THE SYNTHESIS OF 6-FUNCTIONALIZED 4(3H)-PYRIMIDINONES, Tetrahedron letters, 38(25), 1997, pp. 4343-4346
The reaction of 6-trifluoromethanesulfonyloxy-4(3H)-pyrimidinones with
Me2Cu(CN)Li-2, and with vinyl tributyltin, trimethylsilylacetylene, a
nd zinc cyanide with palladium catalysis, are described for the synthe
sis of a variety of fully functionalized 6-substituted-4(3H)-pyrimidin
ones of interest as herbicides.
