PROCESS FOR THE PREPARATION OF 1,1,3,3-TETRAALKYLISOINDOLINE STARTING FROM N-BENZYLPHTHALIMIDE |
摘要 |
<p>Process for the preparation of 1,1,3,3-tetra-alkyl derivatives of isoindoline which comprises the transformation of N-benzylphthalimide into N-benzyl-1,1,3,3-tetra-alkylisoindoline by means of treatment with a Grignard reagent prepared in methyl-tert-butyl ether starting from magnesium and an alkyl halide and subjecting the intermediate thus obtained to a hydrogenolysis reaction in the presence of hydrogen and a catalyst based on supported palladium.</p> |
