We have examined whether the allyl halide cross-metathesis reaction tolerates alpha-alkoxy amide groups. Ruthenium-based catalysts I-Ill did not catalyze the cross-metathesis of allyl halides in the presence of an alpha-alkoxy N,N-dimethylamide group to any appreciable extent, but the reaction could tolerate either a bulky N,N-diisopropylamide or Weinreb amide group. In particular, the Grubbs-Hoveyda-Blechert 2nd generation catalyst (III) efficiently catalyzed the cross-metathesis of allyl halides with olefins bearing a Weinreb amide group. (C) 2011 Elsevier Ltd.

generation catalyst (III) efficiently promotes these processes with olefins bearing a Weinreb amide group. Lastly, a reinvestigation of the ester group tolerance of the allyl halide CM with unsaturated esters demonstrated that III serves as an efficient catalyst for these reactions.
