A designed phenylalanyl-tRNA synthetase variant allows efficient in vivo incorporation of aryl ketone functionality into proteins [PDF]

open access: yes, 2002
Incorporation of non-natural amino acids into proteins in vivo expands the scope of protein synthesis and design. p-Acetylphenylalanine was incorporated into recombinant dihydrofolate reductase (DHFR) in Escherichia coli via a computationally designed ...

Conformational modulation of sequence recognition in synthetic macromolecules [PDF]

open access: yes, 2011
The different triplet sequences in high molecular weight aromatic copolyimides comprising pyromellitimide units ("I") flanked by either ether-ketone ("K") or ether-sulfone residues ("S") show different binding strengths for pyrene-based tweezer-molecules.

Synthesis of some novel hydrazono acyclic nucleoside analogues

open access: yesBeilstein Journal of Organic Chemistry, 2010
The syntheses of novel hydrazono acyclic nucleosides similar to miconazole scaffolds are described. In this series of acyclic nucleosides, pyrimidine as well as purine and other azole derivatives replaced the imidazole function in miconazole and the ...

A Facile One-Pot Process for the Formation of Hindered Tertiary Amines

open access: yesMolecules, 2012
A simple and convenient method was developed for the preparation of hindered tertiary amines via direct reductive amination of ketones with secondary aryl amines, using trichlorosilane as reducing agent and tetramethylethylenediamine (TMEDA) as organic ...

Heterogenisation of ketone catalysts within mesoporous supports for asymmetric epoxidation

open access: yes, 2013
The synthesis of the first mesoporous silica (150 Å) anchored carbohydrate-derived chiral ketone is described. This new heterogeneous catalyst has been shown to be effective in the asymmetric epoxidation of olefins by oxone.

Palladium-catalyzed acetylation of arenes. [PDF]

open access: yes, 2014
A simple method for the preparation of aryl methyl ketones is reported. The transformation involves the Pd-catalyzed coupling of an acyl anion equivalent, acetyltrimethylsilane, with aryl bromides to afford the corresponding acetylated arenes in ...
