(β-Amino alcohol)(arene)ruthenium(II)-Catalyzed Asymmetric Transfer Hydrogenation of Functionalized Ketones − Scope, Isolation of the Catalytic Intermediates, and Deactivation Processes
Kathelyne Everaere,André Mortreux,Michel Bulliard,Johannes Brussee,Arne van der Gen,Guy Nowogrocki,Jean-François Carpentier +6 more
TL;DR: In this article, the asymmetric transfer hydrogenation of functionalized ketones with (β-amino alcohol)(arene)RuII catalysts using 2-propanol as the hydrogen source has been studied.
Journal ArticleDOI
Encapsulation and characterization of proton-bound amine homodimers in a water-soluble, self-assembled supramolecular host
TL;DR: Both G3(MP2)B3 and G3B3 calculations were used to investigate the enthalpy of the hydrogen bond in the proton-bound homodimers and suggest that theEnthalpic gain upon formation of the pro tonic bond may drive guest encapsulation.

An efficient synthesis of (R)-(+)- and (S)-(-)-propranolol from resolved 5-idomethyloxazo-lidin-2-ones
TL;DR: In this paper, an empirical correlation of configuration and 1H NMR chemical shift for alternate diastereomers has been devised and has proved to be applicable in assigning the configuration of 5-substituted 3-(1'-phenyleth-1'-yl)oxazalidin-2-ones.

Highly enantioselective protonation of photodienols an unusual substituent effect on the induced chirality
Olivier Piva,Jean-Pierre Pete +1 more
TL;DR: In this paper, a photodeconjugation of α, β -unsaturated esters or lactones using catalytic amounts of new chiral cyclic inductors derived from (+) camphor is described.

TL;DR: Two thymidine hypermodifications are found and the discovery and characterization of two bases, 5-(2-aminoethoxy)methyluridine (5-NeOmdU) and 5-NedU, in the virion DNA of ViI and M6 phages, respectively, point to an unexplored diversity of DNA modifications and the underlying biochemistry of their formation.
