The use of Pseudomonas stutzerilipase (PSL) as a biocatalyst for aminolysis reactions with bulky substrates has been investigated. PSL compared favorably to Novozym® 435 (immobilized Candida antarcticalipase B, NOV435) in the aminolysis of various bulky methyl esters and amines. While NOV435 demonstrated a higher rate of aminolysis with methyl 2-phenylpropionic acid as the acyl donor, PSL outperformed

The invention relates to macrocyclic metal complexes and their production and use for the production of conjugates with biomolecules. The conjugates are suitable as contrast media in NMR diagnosis and radiodiagnosis as well as for radiotherapy. High relaxivity is achieved by a special liganding of macrocyclic compounds, and a fine-tuning of the relaxivity is made possible.

An efficient aminocarbonylation of N-tosylhydrazones derived from aromatic aldehydes and ketones mediated by molybdenum hexacarbonyl is reported. This method is palladium-free and provides a rapid access to the alpha-aryl acetamides in moderate to good yields. (C) 2013 Elsevier Ltd. All rights reserved.
