A facile hydrogenation-induced self-assembly strategy to synthesize lithium hydride (LiH) nanosheets with a thickness of 2 nm that are uniformly distributed on graphene is reported and designed. Taking advantage of LiH nanosheets with high reactivity and a homogeneous distribution on graphene support as a nanoreactor, the confined chemical synthesis of oxygen-free lithiated composites is effect...

One element of structure that invariably increases the difficulty of a chemical synthesis is the presence in the target molecule of contiguous all-carbon quaternary stereocenters. This Perspective will examine the most useful transformations and strategies devised recently for directly assembling this structural unit.

2'(3')-O-L-Phenylalanylderivatives of fluorescent 1,N6-ethenoadenosine and 3,N4-ethenocytidine were prepared by chemical synthesis. Both compounds are good acceptor substrates in ribosomal peptidyltransferase reactions. Since these compounds cannot form Watson-Crick base pairs, the results indicate that the terminal aminoacyladenosine unit of AA-tRNA is bound to ribosomal protein on the accepto...

Databases dedicated to predicted inorganic crystal structures are emerging fast. Possible applications are listed, from identification through the powder diffraction pattern fingerprint, leading to crystal structure determination before estimation of the cell parameters of newly synthesized real compounds, to the prediction of interesting properties of still unknown materials, allowing chemical...

Molecular self-assembly is the spontaneous association of molecules under equilibrium conditions into stable, structurally well-defined aggregates joined by noncovalent bonds. Molecular self-assembly is ubiquitous in biological systems and underlies the formation of a wide variety of complex biological structures. Understanding self-assembly and the associated noncovalent interactions that conn...

A synthetic strategy combining automated solid-phase chemical synthesis and enzymatic sialylation was developed to access α(2,3)-sialylated glycans.

Traditionally, access to structurally defined complex carbohydrates has been very laborious. Although recent advancements in solid-phase synthesis have made the construction of complex oligosaccharides less tedious, a high level of technical expertise is still necessary to obtain the desired structures. We describe the automated chemical synthesis of several oligosaccharides on a solid-phase sy...
