Highly Chemoselective Pd−C Catalytic Hydrodechlorination Leading to the Highly Efficient N-Debenzylation of Benzylamines
摘要:
In the presence of 1,1,2-trichloroethane, a novel procedure for the Pd-C catalytic N-debenzylation of benzylamines was established. The method proceeded in a synergistic catalytic system and directly gave the products as crystal amine hydrochlorides in practically quantitative yields.

A new metallo-β-lactamase inhibitor which acts as a medicament for inhibiting the inactivation of β-lactam antibiotics and recovering anti-bacterial activities is disclosed. The maleic acid derivatives having the general formula (I) have metallo-β-lactamase inhibiting activities. It is possible to recover the anti-bacterial activities of β-lactam antibiotics against metallo-β-lactamase producing bacteria by combining the compound of the general formula (I) with β-lactam antibiotics.
