Organic Chemistry


The Wittig—Horner reaction of CbzNHCH(CO2Me)P(O)(OMe)2 (1) with ArCHO (2) in the presence of Et3N as a base affords methyl (Z)-3-aryl-2-(carbobenzoxyamino)acrylates (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.
