Herein, we present hitherto unknown crystal structures of naphthalene-N,N-bis(2-picolyl)amide [NaphBPA] and its CuCl2-, CuBr2-, Cu(OTf)2-, and ZnCl2-complexes. In each CuII-complex, we obtained an unusual coordination mode which involves the amide ni

Herein, we present a new methodology for preparing 6-membered ring carbamates from a Cu I -promoted cyclization of N , N -bis(2-picolyl)amine substituted ureas. The reactions work best in the presence of up to five-fold excess of CuCl at room tempera

The synthesis of 'head-to-tail' cyclized peptides requires orthogonal protecting groups. Herein, we report on the introduction of bis(2-pyridylmethyl)amine (Bpa) as a new protecting group for carboxylic functions in SPPS. The synthesis of the Bpa-pro

We describe a general and versatile approach for the conversion of carboxylic acid amides into their corresponding esters despite the fact that the former are thermodynamically more stable. The transformations are mediated by the coordination of CuI

We describe the modulation of catalytic activities by adjacent chelating entities as a new and hitherto unknown principle. It is demonstrated for ring-closing metathesis (RCM) as well as for cross metathesis (CM) reactions. For this purpose, we have
