From January 2014 onwards, all Communications in Asian Journal of Organic Chemistry will contain an abstract as their first paragraph. We therefore request that every new Communication be submitted with such an abstract. When you write the abstract, please keep the following aspects in mind (they can be found in more detail in the Author Guidelines, Section 2.3.): In the abstract, the motivation for the work, the methods applied, the results, and the conclusions drawn should be presented (maximum 1000 characters). The abstract should contain several keywords to aid finding the paper online, and it should not mention graphical elements, tables, or references within the paper.

Build me up: Two mixed-stack charge-transfer (CT) nanostructures of perylene and tetrathiafulvalene donors with viologen acceptors were constructed by noncovalent amphiphilic self-assembly design. Irrespective of the viologens’ morphology, CT amphiphiles self-assemble into 1D nanostructures and show impressive conductivity without any external doping.

Out of metal! A metal- and oxidant-free method for direct sp3 CH arylation of pyrrolidine has been developed. As an alternative to metal-mediated reactions, the method relies on a highly atom economic three-component reaction, which is selective for single regioisomers of aryl pyrrolidines that are important in chemistry as well as in biology. The method, operating under simple and mild reaction conditions, is very efficient, even on a multigram scale.

Hit for six: (±)-Stemoamide was synthesized in six steps starting from readily accessible 2-trimethylsilioxy-3-methylfuran, methyl-4-nitrobutyrate, and acrolein after converting the nitro group into a ketone and a subsequent reductive amination.

A [2+2] cycloaddition reaction of allene-ynes under thermal conditions with/without a metal complex is described. A key feature of this reaction is that a 2-benzothiazolylphenyl group bearing a CC triple bonds remarkably promotes the reaction to give the corresponding cyclobutenes with or without metal catalysts.

Surprise! An organocatalytic enantioselective Friedel–Crafts alkylation of 1-naphthols with isatins is reported. The process, catalyzed by a simple cinchona-alkaloid-derived thiourea, gives 3-(naphthalen-2-yl)-3-hydroxy-2-oxindoles. An unexpected intramolecular dehydration reaction occurs spontaneously with 4-substituted 1-naphthols to give structurally different ketone oxindoles. Ts=toulenesulfonyl.
