      Affinity chromatography (AC) using ligand-immobilized bead technology is generally the first choice for target exploration. However, a moderately bioactive ligand, such as endogenous bioactive metabolites, is expected to cause difficulties in AC-based target detection because AC is highly dependent to extremely high affinity between ligand and target. As described in their Full Paper on 3286 ff., M. Ueda et al. report that a compact molecular probe (CMP) strategy has proven to be effective for detection of a moderate-affinity target for which AC cannot be applied successfully. We applied this CMP strategy for the target identification of potassium isolespedezate that showed moderate leaf-opening activity (10−5–10−6M). By using this CMP approach, the cytosolic target protein, Cassia obtusifolia MetE, was detected and isolated as a single band.

    1. Inside Cover: One-Pot Multimolecular Macrocyclization for the Expedient Synthesis of Macrocyclic Aromatic Pentamers by a Chain Growth Mechanism (Chem. Asian J. 12/2011) (page 3162)

      Bo Qin, Sheng Shen, Chang Sun, Dr. Zhiyun Du, Prof. Dr. Kun Zhang and Dr. Huaqiang Zeng

      Version of Record online: 29 NOV 2011 | DOI: 10.1002/asia.201190051

      One-pot hydrogen-bonding-assisted macrocyclizations have received considerable recent interest due to their already proven and other potentially realizable functions and applications. Mechanistic investigations on one-pot macrocyclizations, however, are scarce. In their Full Paper on page 3298 ff, H. Q. Zeng et al. demonstrate, for the first time, the applicability of a chain-growth mechanism to the POCl3-mediated one-pot macrocyclization reaction, allowing for the highly selective formation of five-residue macrocycles formed by the successive addition of bifunctional monomer units onto the growing oligomeric backbone.

    1. Elimination Reactions

      Heuristic Chemistry—Elimination Reactions (pages 3180–3188)

      Dr. Nicole Graulich, Prof. Dr. Henning Hopf and Prof. Dr. Peter R. Schreiner

      Version of Record online: 29 JUL 2011 | DOI: 10.1002/asia.201100110

      Thumbnail image of graphical abstract

      A little common sense goes a long way! Recurrent motifs and patterns of various elimination reactions in organic synthesis are discussed. We derive and exemplify heuristic guidelines for describing and predicting elimination reactions with classical and contemporary transformations. Heuristic principles allow an easier classification of reactions, bring order to diversity, and encourage a change in how we teach and perceive organic chemistry.

      Thumbnail image of graphical abstract

      TA for now: Tethered aminohydroxylation (TA) cyclic stereocontrol is possible in the catalytic TA reaction of acyclic systems that bear an exocyclic stereodirecting group. The influence of the alkene substitution pattern and the role of the protecting group on the allylic alcohol are both explored. A model is also presented to rationalize the observed trends in stereoselectivity.

      Thumbnail image of graphical abstract

      An electrochemically highly amphoteric nanographene was synthesized and characterized experimentally and theoretically. The synthetic strategy involves the attainment of a tetrathiafulvalene (TTF) derivative with two diamine moieties, which also plays a crucial role in the development of diverse TTF-based functional materials. The direct fusion of ovalene units with the TTF core dramatically enhances the intermolecular π–π interactions (see graphic).

    15. Mixed-Valent Compounds
