Bicyclic Peptide Antagonists Derived from Genetically Encoded Combinatorial Libraries

open access: yesCHIMIA, 2011
Ligands based on bicyclic peptides can combine favourable properties of antibodies (good binding affinity and target specificity) and small molecule ligands (stability, access to chemical synthesis, diffusion properties) and might be suitable ...

Flexible access to conformationally-locked bicyclic morpholines [PDF]

open access: yes, 2013
A preparatively accessible route to a series of conformationally-locked bicyclic morpholines has been developed. This flexible approach allows for diversification in order for a small array of lead-like scaffolds to be synthesised from readily available ...

Crystal structure and Hirshfeld surface analysis of 2,2,2-trifluoro-1-(7-methylimidazo[1,2-a]pyridin-3-yl)ethan-1-one

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2022
The bicyclic imidazo[1,2-a]pyridine core in the molecule of the title compound, C10H7F3N2O, is planar within 0.004 (1) Å. In the crystal, the molecules are linked by pairs of C—H...N and C—H...O hydrogen bonds, forming strips.

Target identification strategies in plant chemical biology [PDF]

open access: yes, 2014
The current needs to understand gene function in plant biology increasingly require more dynamic and conditional approaches opposed to classic genetic strategies.

Ethyl 3-amino-2-cyano-4-(4-methoxyphenyl)-6- methylthieno[2,3-b]pyridine-5-carboxylate

open access: yesIUCrData, 2017
In the title molecule, C19H17N3O3S, the bicyclic core is planar [maximum deviation = 0.0205 (1) Å] In the crystal, the molecules stack along the a-axis direction through π–π-stacking interactions between the bicyclic units with a small alternation in the

Stereodivergent, Diels-Alder-initiated organocascades employing α,β-unsaturated acylammonium salts: scope, mechanism, and application. [PDF]

open access: yes, 2017
Chiral α,β-unsaturated acylammonium salts are novel dienophiles enabling enantioselective Diels-Alder-lactonization (DAL) organocascades leading to cis- and trans-fused, bicyclic γ- and δ-lactones from readily prepared dienes, commodity acid chlorides ...

The fluorine-NHC gauche effect: a structural and computational study [PDF]

open access: yes, 2013
Herein, we report the synthesis and X-ray structural analysis of a collection of fluorinated metal N-heterocyclic carbenes (Ag, Au, Pd, Rh, Ir) and their precursor salts.

6-Methylsulfanyl-4H-pyrimido[1,6-a]pyrimidin-4-one

open access: yesActa Crystallographica Section E, 2009
Reaction of 2-(methylsulfanyl)pyrimidin-4-amine with the 5-(methoxyvinylidene) derivative of Meldrum's acid and subsequent heating of the product in Dowtherm fluid yielded the title compound, C8H7N3OS, which was proven to contain a bicyclic 4H-pyrimido[1,

Stereoisomerism in pentaerythritol-bridged cyclotriphosphazene tri-spiranes: spiro and ansa 1,3-propanediyldioxy disubstituted derivatives [PDF]

open access: yes, 2005
Four isomeric products were isolated and purified from the reaction of 1,3-propanediol with the tetra-spirane cyclophosphazene-organophosphate compound (1): viz. the di-monospiro (2a), di-monoansa (2b) and two monospiro-monoansa derivatives (2c) and (2d).

Diethyl 3-amino-6-methyl-4-[(E)-2-phenylethenyl]thieno[2,3-b]pyridine-2,5-dicarboxylate

open access: yesIUCrData, 2016
In the title molecule, C22H22N2O4S, the bicyclic core is slightly folded [1.9 (1)°], while pairwise intermolecular N—H...O hydrogen bonding forms dimers across centers of symmetry.
