Hi ! A few days ago, I had posted for making a michael adduct from a keto ester & l-alanine. At that time, I mistaken taking the ketoester (ethyl-3-benzoylacrylate). It should be Ethyl-2-oxo-4-phenylbutyrate as under. And the references suggests instead of making the michael adduct, to make an imine between both these reactants (the ketoester & l-alanine) & then reducing the imine to get my final product. Here, I again clarify this IMINE FORMATION mechanism : PhCH2CH2C=OCOOC2H5 + H2N-CH(CH3)-COOH makes : PhCH2CH2-C(COOC2H5)=N-CH(CH3)-COOH. CAN YOU SUGGEST ME HOW I CAN PERFORM THIS REACTION ? i.e., solvent media, reaction conditions, etc. Awaiting your replies....... shrent
