An efficient Pd/Zn co-catalyzed chemo-selective hydrogenation of α-methylene-γ-keto carboxylic acids is described. This methodology offers a divergent synthesis of α-methyl-γ-keto carboxylic acids, α-methylcarboxylic acids, and lactones starting from α-methylene-γ-keto carboxylic acids via selectivehydrogenation by varying the catalytic conditions avoiding the use of high pressure of hydrogen.
