Monodentate Transient Directing Group Enabled Pd-Catalyzed Ortho-C-H Methoxylation and Chlorination of Benzaldehydes

We report Pd-catalyzed ortho-C-H methoxylation and chlorination of benzaldehydes by employing monodentate transient directing groups (TDGs) as an alternative strategy to bidentate TDGs. More importantly, a single crystal of benzaldehyde imine ortho-cyclopalladium intermediate was successfully obtained, and its structure was unambiguously determined by X-ray diffraction, which clearly showed that it was a binuclear palladium species bridged by a pyridone ligand. The utility of this approach was further demonstrated through the synthesis of key intermediates of natural products and drugs.

METHOD FOR THE PRODUCTION OF LOSARTAN

The invention relates to a novel method for the production of losartan, an imidazol derivative with the chemical name 2-n-butyl-4-chloro-5-hydroxymethyl-1-{[2'-(1H-tetrazol-5-yl)biphenyl-4-]methyl}imidazol and the pharmacologically active salts thereof. The invention also relates to novel intermediate products which are suitable for the production of losartan, and to novel methods for the production of intermediate compounds which are suitable for the production of losartan. One aspect of the invention is a method for the production of a compound of general formula (I), which can arise as an intermediate step in the inventive representation of losartan.
