Novel functionalized analogues of the biologically active nucleoside, nebularine, have been synthesized. The key step of the syntheses involved palladium-catalyzed cross-coupling reactions between 2-iodonebularine and organostannanes. This synthetic approach has considerable potential generality, and the only limitation appears to be the availability of the appropriate organostannane coupling reagent.
