An Efficient Synthesis of 2-(((9-Fluorenylmethoxycarbonyl)amino)methyl)benzoic Acid
摘要:
An efficient, two-step syntesis of the title compound 3 in 61% overall yield is presented. The synthesis involves hydrazine removal of the N-phthalimide protecting group of alpha-phthalimido-o-toluic acid (6), followed by N-Fmoc formation with (9-fluorenylmethyl)succinimidyl carbonate.

We report a Cu/Fe co‐catalyzed Ritter‐type C−H activation/amination reaction that allows efficient and selective intermolecular functionalization of benzylic C−H bonds. This new reaction is featured by simple reaction conditions, readily available reagents and general substrate scope, allowing facile synthesis of biologically interesting nitrogen containing heterocycles. The Cu and Fe salts were found

The rapid synthesis of valuable isoindolinones with cheap and easily available starting materials undermildconditions is of great importance, but is challenging. We enclose here a novel electrochemical strategy to selectively and sustainably access isoindolinone using simple o-alkyl benzoic acids and nitriles as substrates under metal catalyst and external oxidant-free conditions. The protocol shows
