Significance
The authors describe a 1,3-rearrangement of 2,3-allenylcarboxylates 1 to afford 3,4-disubstituted butadienylcarboxylates 2 under rhodium catalysis. This work is quite similar to a gold-catalyzed rearrangement reported by Gagosz and co-workers (Org. Lett. 2007, 9, 985), but the stereoselectivity for the E-alkene is considerably better.
