  1. Enantioselective Synthesis of Tertiary Propargylic Alcohols under N-Heterocyclic Carbene Catalysis

    Ynones give the best: The enantioselective cross-benzoin reaction between aldehydes and ynones by employing a chiral N-heterocyclic carbene (NHC) as catalyst proceeds cleanly, not observing any byproduct arising from competitive Stetter-type reactivity. This procedure allows the preparation of tertiary alkynyl carbinols as highly enantioenriched materials, which have the remarkable potential to be used as chiral building blocks in organic synthesis.

  2. Palladium-Catalyzed Construction of Heteroatom-Containing π-Conjugated Systems by Intramolecular Oxidative C[BOND]H/C[BOND]H Coupling Reaction

    Up the ladder: Synthesis of heteroatom-containing ladder-type π-conjugated molecules was successfully achieved via palladium-catalyzed intramolecular oxidative C[BOND]H/C[BOND]H cross-coupling reaction (see scheme). This reaction provides a variety of π-conjugated molecules bearing heteroatoms, such as nitrogen, oxygen, phosphorus, and sulfur atoms, and a carbonyl group.

  3. Template-Dependent Photochemical Reactivity of Molecular Metal Oxides

    Dr. Johannes Tucher, Dr. Katrin Peuntinger, Johannes T. Margraf, Prof. Dr. Timothy Clark, Prof. Dr. Dirk M. Guldi and Prof. Dr. Carsten Streb

    The inside counts! Photochemical reactivity enhancement in two isostructural bismuth vanadium oxide clusters is observed by exchange of the central template anion. Computational and spectroscopic analyses suggest that the heavier bromide template enables a more efficient spin-orbit-coupling, leading to faster singlet-triplet transition.

  4. Construction of the Isocopalane Skeleton: Application of a Desulfinylative 1,7-Hydrogen Atom Transfer Strategy

    Xiong Xiao, ZhongYu Xu, Qian-Ding Zeng, Dr. Xi-Bo Chen, Wen-Hao Ji, Prof. Dr. Ying Han, PeiYing Wu, Dr. Jiangmeng Ren and Prof. Dr. Bu-Bing Zeng

    Get ahead, get a HAT: A novel ring-closing reaction of allylic sodium sulfonate and an intramolecular redox reaction of sulfonyl chloride facilitate efficient access to polycyclic products from naturally abundant andrographolide. Two promising isocopalane diterpene chirons are obtained, which could be further used to synthesize a series of natural isocopalane derivatives or enantiomers of spongianes.

  5. Dienamine and Friedel–Crafts One-Pot Synthesis, and Antitumor Evaluation of Diheteroarylalkanals

    All in one: An asymmetric synthesis of diheteroarylalkanals through a one-pot dienamine and Friedel–Crafts reaction is presented (see scheme). The reaction tolerates a large variety of substituents at different positions of the starting aldehyde, and the use nucleophiles and different diheterocyclic alkanals can also be achieved. The antiproliferative activity of these new compounds in different cancer tumor cell lines has also been investigated and it was found that, with the appropriate substitution, the compounds are as cytotoxic as Cisplatin.
