| Abstract: | An asymmetric synthesis of chiral N-substituted 3-methylisoindolin-1-ones was performed using the Pd0-catalyzed diastereoselective hydrogenation of their 3-methylene-substituted precursors, that has not been investigated earlier. The highest diastereoselectivity (67% de) was achieved when the hydrogenation was carried out in methanol mediated by a palladium catalyst (Pd/C) modified with cinchonidine. |
