The enantiomeric excess is a key parameter for chemical and pharmaceutical industries for its ability to determine the activity and therapeutic action of chiral compounds. The determination of the enantiomeric excess using nuclear magnetic resonance is generally based on the formation of diastereomeric complexes. Herein we report novel chiral oxo-bridged calix[2]arene[2]triazine derivatives, which were synthesized from (1S,2R)-(-)-1-amino-2-indanol or (1S,2R)-(+)-2-amino-1,2-diphenylethanol. The structures of these compounds were established by various spectroscopic methods. Their enantiomeric recognition abilities towards the enantiomers of alpha-racemic carboxylic acids were examined by using 1H NMR spectroscopy. The DeltaDeltadelta values of alpha-H signals were appropriate to give a good baseline resolution for most of the tested analytes, which ranged from 0.005 to 0.053 ppm. The alpha-hydroxy acids, especially those containing aromatic group such as mandelic acid, alpha-methoxyphenylacetic acid, showed a bigger DeltaDeltadelta value in comparison to the other carboxylic acids.

Herein, we report the first example of the asymmetric hydrogenation of a prochiral benzodiazepine substrate as key transformation in a pilot-scale synthesis of BET inhibitor BAY 1238097. High-throughput screening in a parallel reactor enabled us to identify an efficient catalyst based on Ir and a chiral bisphosphine. An additive screening allowed significant reduction of catalyst loading. Ultimately, the hydrogenation was performed on a kilogram scale leading to the production of 27 kg of the desired product with an enantiomeric excess of 99% after crystallization.

The pyrolysis of tobacco waste, including tobacco leaf (TL) and tobacco stems (TS), using a fluid bed reactor was investigated for the preparation of bio-oil containing aroma compounds or for use as a liquid fuel. The maximum bio-oil yield from TS was 67.47%, and was higher than that from TL. The bio-oil compositions were analyzed by gas chromatography?mass spectrometry (GC?MS) and can be classified into 10 groups, of which heterocyclic compounds and acids are the most abundant substances from both TL and TS. The oil from TL contains more aroma components with a sweet or tobacco flavor responsible for the cigarette sensory taste. Both oils from the pyrolysis of the two tobacco samples have fewer harmful components than tobacco smoke. The effects of the pyrolysis temperature on the bio-oil composition were also investigated. Most aroma components were obtained at a temperature below 350 ?, which would broke into small molecular compounds as the temperature increased because of secondary decomposition.

An expeditious synthetic approach to chiral phenol 1, a key building block in the preparation of a series of drug candidates, is reported. The strategy includes a cost-effective and readily scalable route to cyclopentanone 3 from isobutyronitrile (10). The sterically hindered and enolizable ketone 3 was subsequently employed in a challenging Grignard addition mediated by LaCl 3?2LiCl. A novel preparation of the lanthanide reagent required for this transformation is described. To complete the process, a highly enantioselective hydrogenation step afforded the target (1). The importance of the phenol group to the success of this asymmetric transformation is discussed.
