W. L. Hough and R. D. Rogers*
[Full Text PDF(J-STAGE)] [Supporting Information]
Ionic liquids have evolved from their original uses based on their tunable physical properties to unique materials based on their chemical properties and now to active pharmaceutical ingredients based on their biological properties. It seems that the only limit to their applications is one′s imagination.

S. Weber and R. Bittl*
[Full Text PDF(J-STAGE)]
Electron paramagnetic resonance (EPR) and electron-nuclear double resonance (ENDOR) are important tools to elucidate structural and electronic aspects of paramagnetic cofactors in proteins. In this account, emphasis is given to in-depth EPR/ENDOR characterizations of the quinone-type and flavin cofactors in ethanol dehydrogenase and photolyase, and the relative positioning of substrates.

P. Y. W. Dankers and E. W. Meijer*
[Full Text PDF(J-STAGE)]
|
|
Supramolecular biomaterials can be obtained via a modular, self-assembly approach using hydrogen-bonded supramolecular polymers or self-assembling oligopeptide fibers. This results in materials that fulfil the biomaterials trinity of tuneable mechanical properties, degradability and bioactivity, and importantly are dynamic in nature.

[Full Text PDF(J-STAGE)]
The CuI-catalyzed Huisgen 1,3-dipolar cycloaddition can be used in the efficient and divergent synthesis of mechanically interlocked molecules, such as [n]rotaxanes and [2]catenanes. The simplicity of the required precursors and the straight-forwardness of the reaction establish this type of “click chemistry” as an indispensable strategy for the synthesis of mechanically interlocked molecular compounds.

[Full Text PDF(J-STAGE)]
Hydroxycarbonyl compounds are valuable intermediates in asymmetric synthesis, particularly in the preparation of complex structures such as terpenes, carbohydrates, and alkaloids. In addition, the use of chiral glycolic acid equivalents has been the approach of choice for α-hydroxycarbonyl-containing natural products such as herbarumin II and rapamycin.

[Full Text PDF(J-STAGE)]
he application of substituted 1-lithio-1,3-dienes as building blocks for the preparation of cyclic compounds and linear compounds are briefly summarized. Results have revealed that the essential factor which makes 1-lithio-1,3-diene derivatives useful and unique as building blocks is the intra-cooperation between the alkenyllithium moiety and the butadienyl skeleton.

S. Kim* and S. Kim
[Full Text PDF(J-STAGE)]
Tin-free radical reactions based on α-scission of alkylsulfonyl radicals are very useful for various carbon–carbon bond formations. Especially, alkyl allyl sulfone precursors are highly efficient and most reliable to generate primary alkyl radicals under tin-free conditions for the further formation of carbon–carbon bonds.
