(matrix presented) Novel peptidomimetics of the antifungal cyclic peptide Rhodopeptin were synthesized. As with the cyclic peptides, the presence of all three Rhodopeptin side chains was found to be indispensable for peptidomimetic activity. We discovered

A method for the intermolecular hydroamination of 2-alkynylanilines in a planetary ball mill is described, which avoids the use of solvents during the reaction. Different additives were tested, whereby ZnBr2 in stoichiometric amounts showed the best performance in terms of yield and selectivity. Furthermore, the materials used for milling balls and beakers as well as the milling time and the rotation frequency were changed in order to achieve the best reaction conditions. As a result, two methods for the synthesis of 2-substituted 1H-indoles are described with their respective advantages and disadvantages. Both methods were used to convert different alkyl and aryl containing 2-ethynylanilines. This journal is the Partner Organisations 2014.
