Characterization of the novel ene reductase Ppo-Er1 from paenibacillus polymyxa [PDF]
, 2020 Ene reductases enable the asymmetric hydrogenation of activated alkenes allowing the manufacture of valuable chiral products. The enzymes complement existing metal- and organocatalytic approaches for the stereoselective reduction of activated C=C double ...

Asymmetric microbial reduction of ketones: absolute configuration of trans-4-ethyl-1-(1S-hydroxyethyl)cyclohexanol [PDF]
, 2009 A set of five fungal species, Botrytis cinerea, Trichoderma viride and Eutypa lata, and the endophytic fungi Colletotrichum crassipes and Xylaria sp., was used in screening for microbial biocatalysts to detect monooxygenase and alcohol dehydrogenase ...

Chiral thiols. Synthesis and enantiomeric excess determination
, 1987 Chiral thiols are a class of chira compounds, which is gaining mone and nore attention the last decenniun. Especially α-mercaptocarboxylic acids are frequently found as a structunal unit in (biologically) important products. As a consequence, many synthetic analoga or derivatives of these natural products, but also other organosulfur compounds, have ...

Remote conformational responses to enantiomeric excess in carboxylate-binding dynamic foldamers.
Chemical Communications, 2019 A crystallographically characterised zinc(ii)-capped foldamer can sense the enantiomeric excess of scalemic carboxylate solutions, including those produced by enantioselective organocatalysis, and can relay this input signal along the foldamer body to a ...

Effects of Water Addition on a Catalytic Fluorination of Dienamine
Molecules, 2019 We investigate the effects of water addition on a highly stereocontrolled fluorination of dienamine generated by α-branched enals and 6′-hydroxy-9-amino-9-deoxy-epi-quinidine with N-fluorobenzenesulfonimide (NFSI) in the presence of Brø ...

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin
Angewandte Chemie, EarlyView.Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.

Homochiral Acyl Isocyanates as Diagnostic NMR Probes for the Enantiomeric Purity of Chiral Alcohols
Sultan Qaboos University Journal for Science, 2000 The first reported acyl and sulfonylisocyanates were developed and tested in reactions with chiral alcohols to afford diastereomeric carbamates. NMR analysis of these investigates the chemical shift discrimination that would allow these activated ...
