Carboxylic acids containing electron withdrawing groups

Similar additions have been successfully carried out with carboxylic acids, anhydrides, acyl halides, carboxylic esters, nitriles, and other types of compounds. These reactions are not successful when the alkene contains electron-withdrawing groups such as halo or carbonyl groups. A free-radical initiator is required, usually peroxides or UV light. The mechanism is illustrated for aldehydes but is similar for the other compounds ... [Pg.1034]

The final quadrant, the top right-hand, has to contain an electron withdrawing group. This group activates the carbon-carbon unsaturation. A wide variety of groups are tolerated including a carboxylic acid, ester, amide, nitrile, ketone, and aldehydes [7, 9]. This shows that the catalyst system can be used to prepare a wide range of amino acid derivatives without recourse to a number of transformations on the product unnatural amino acid. [Pg.261]
