The Wittig-Horner reaction of CbzNHCH(CO(2)Me)P(O)(OMe)(2) (1) with ArCHO (2) in the presence of Et(3)N as a base affords methyl (Z)-3-aryl-2-(carbobenzoxyamino)acrylate (3) with high degrees of diastereoselectivity (Z)/(E) > 10:1. One recrystallization of the crude product is sufficient to obtain isomerically and chemically pure (Z)-3.
