Angewandte Chemie 11/2011: Functional and Suitable

Author: Angewandte Chemie International Edition

In the Review in this issue, G. Rousseau and B. Breit discuss removable directing groups in organic synthesis and catalysis. What do you do if the existing functional group within a substrate is unsuited to achieve an efficient intramolecular reagent/catalyst delivery? In a Minireview, E. Meggers describes conventional and unusual enzyme inhibitor scaffolds. The Highlights deal with the metal-free synthesis of pyridines (K. Kral and M. Hapke), aromaticity in porphyrinoids (M. Bröring), and a chlorophyll with strongly red-shifted absorption (B. Kräutler).

In the Communications section, R. G. Cooks et al. present a synchronized mass spectrometry protocol with well-orchestrated microdroplet creation, nebulizing gas pulsing, and DAPI interface opening. N. Houbenov et al. succeeded in the preparation of a polymeric supramolecular framework solid with self-assembled cages based on two orthogonal shape-persistent motifs: alpha helix and beta sheet (see picture). P. Jena et al. discovered a series of magnetic superhalogens formed of (MnxCl2x+1) units and characterized it by photoelectron spectroscopy, mass spectrometry, and theoretical studies.
