Azonia spiro polyaza macrocycles containing biphenyl subunits as anion and cation receptors
Elsevier (2011-06-24)The reaction of N-Boc triprotected cyclam with bis(chloromethyl)biphenyl followed by the corresponding deprotection of the nitrogen atoms allows the preparation of receptor 3 containing an azonia spiro subunit. This receptor ... -
Designed folding of pseudopeptides: the transformation of a configurationally driven preorganization into a stereoselective multicomponent macrocyclization
VCH Verlagsgesellschaf (2008)The efficient synthesis of large-ring pseudopeptidic macrocycles through a multicomponent [2+2] reductive amination reaction is described. The reaction was entirely governed by the structural information contained in the ... -
Structurally disfavoured pseudopeptidic macrocycles through anion templation
Royal Society of Chemistry (2010-08-23)An anionic dicarboxylate is able to template the formation of geometrically disfavoured macrocycles from a dynamic covalent mixture of open chain oligoimines. -
Template Effects in SN2 Displacements for the Preparation of Pseudopeptidic Macrocycles
Wiley (2012-02)Macrocyclisation reactions of C2-symmetric pseudopeptides containing central pyridine-derived spacers are affected by the presence of different anions. The selection of the proper anion gives excellent results for the ...
