Highly chemoselective Pd-C catalytic hydrodechlorination leading to the highly efficient N-debenzylation of benzylamines

(Equation Presented) 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.

Modular syntheses of multidentate ligands with variable N-donors: Applications to tri- and tetracopper(i) complexes

A general method for the preparation of multidentate ligands comprised of a multi-imine platform derived from 1,1,1-tris(aminomethyl)ethane or tris(aminoethyl)amine connected to bi- and tridentate N-donor chelates has been developed. The feasibility of the method has been demonstrated through the synthesis and characterization of a large set of these ligand types. Complexation to Cu(i) was accomplished for several cases, yielding tri- and tetracopper(i) complexes that have been characterized in solution by NMR spectroscopy and conductivity, and in the solid state by elemental analysis, mass spectrometry, and/or X-ray crystallography. These complexes are potentially useful for modeling multicopper protein active sites. The Royal Society of Chemistry.

REACTION OF CYCLIC THIOUREAS WITH CHLOROACYLPIPERAZINES

S-Alkylation products are formed in the reaction of tetrahydropyrimidine-2-thione and hexahydro-1,3-diazepine-2-thione with chloroacylpiperazines in dimethylformamide at room temperature; dihydrothiazolopyrimidine and tetrahydrothiazolo-diazepine systems are obtained in refluxing ethanol.It is shown that the S-alkyl derivatives are very readily converted to condensed systems.
