Palladium-catalyzed cross-coupling of aryldiazonium tetrafluoroborate salts with arylboronic esters
Willis,Strongin
, p. 6271 - 6274 (2000)
A novel palladium-catalyzed reaction of aryldiazonium tetrafluoroborate salts with arylboronic esters furnishes cross-coupled products in moderate yields. The reaction proceeds at relatively mild temperatures and in aqueous media. (C) 2000 Published by Elsevier Science Ltd.

While there is a growing interest in harnessing synergistic effects of more than one metal in catalysis, relatively little is known beyond bimetallic systems. This report describes the straightforward access to an air-stable Pd trimer and presents unambiguous reactivity data of its privileged capability to differentiate C?I over C?Br bonds in C?C bond formations (arylation and alkylation) of polyhalogenated arenes, which typical Pd0 and PdI-PdI catalysts fail to deliver. Experimental and computational reactivity data, including the first location of a transition state for bond activation by the trimer, are presented, supporting direct trimer reactivity to be feasible.
Asymmetric synthesis of an MMP-3 inhibitor incorporating a 2-alkyl succinate motif
Ashcroft, Christopher P.,Challenger, Stephen,Derrick, Andrew M.,Storey, Richard,Thomson, Nicholas M.
, p. 362 - 368 (2013/09/06)
An efficient and practical synthesis is presented of the pharmaceutically active MMP-3 inhibitor UK-370,106 (1) via an olefination/catalytic asymmetric hydrogenation sequence. Commercially available 5-bromo-2-iodotoluene was converted in two steps to the
A potent, selective inhibitor of matrix metalloproteinase-3 for the topical treatment of chronic dermal ulcers
Fray, M. Jonathan,Dickinson, Roger P.,Huggins, John P.,Occleston, Nicholas L.
, p. 3514 - 3525 (2007/10/03)
The pathology of chronic dermal ulcers is characterized by excessive proteolytic activity which degrades extracellular matrix (required for cell migration) and growth factors and their receptors. The overexpression of MMP-3 (stromelysin-1) and MMP-13 (col
