An effective and convenient procedure for the Micha el addition using Fe (acac) 3 (1 mol %) as an effective catalyst, catalyses the Michael addition reaction of nitro me thane to α -cyano cinnamate ester followed by Pinner reaction to produce corresponding diethyl 2-(1-(4-chlorophenyl) -2-nitroethyl)malonate with good yields under mild condition with high yield. Accordingly, we applied this synt hetic strategy for synthesis of (±)- Baclofean
