[GRAPHICS]-Pyridyl- and 5-aryl-2-furaidehydes are prepared from furaldehyde diethyl acetal in a four-step, one-pot procedure: (1) deprotonation; (2) U to Zn transmetalation; (3) Pd-medlated cross-coupling; (4) aldehyde deprotection. Triorganozincate 7 was found to transfer all three groups in the Pd-catalyzed cross-coupling reaction with haloaromatics.
