Molecular Recognition and Assembly. [PDF]
Acta Chemica Scandinavica, 1996 The synthesis and characterization of a series of self-assembling capsules is described. Assembly takes place as a result of the self-complementary hydrogen bonding patterns on the subunit pieces and dimerization occurs in such a manner that the concave surfaces of the two subunits are directed at one another.

Palladium-catalysed formation of vicinal all-carbon quaternary centres via propargylation
Nature Communications, 2016 Formation of vicinal, quaternary stereocentres is challenging, but such products are commonly encountered in nature. Here, the authors report a palladium catalysed process to form vicinal quaternary carbons via propargylation, including in enantiopure ...

Lectin ligands: New insights into their conformations and their dynamic behavior and the discovery of conformer selection by lectins [PDF]
, 1998 The mysteries of the functions of complex glycoconjugates have enthralled scientists over decades. Theoretical considerations have ascribed an enormous capacity to store information to oligosaccharides, In the interplay with lectins sugar-code words of ...

Catalytic enantioselective construction of axial chirality in 1,3-disubstituted allenes
Nature Communications, 2019 Highly enantioselective synthesis of allenes has been relying, so far, on the steric hindrance of substrates. Here the authors achieve excellent stereocontrol in the synthesis of chiral allenes with a palladium-DTBM-SEGPHOS catalytic system in a non ...

Reinforced molecular recognition as an alternative to rigid receptors [PDF]
, 2006 In theory, a perfectly rigid receptor will probably be an unbeatable binder. However, rigidity may not be easy to achieve in practice and it is certainly not Nature’s method to realise high affinity. In many proteins binding affinity is increased through

Nature Communications, 2017 TheLotus japonicus LysM receptor kinase EPR3 perceives rhizobial exopolysaccharides to initiate infection of the root epidermis. Here the authors show that EPR3 also mediates infection thread progression in the root cortex and show that key transcription

Molecular recognition on acoustic wave devices [PDF]
, 1992 Microporous thin films composed either of zeolite crystals embedded in sol-gel derived glass or of a molecular coupling layer, zeolite crystals and a porous silica overlayer, were formed on the gold electrodes of Quartz Crystal Microbalances (QCM). The
