Potassium alkoxides of N-acyl-oxazolidin-2-one-syn-aldols undergo stereoselective elimination reactions to afford a range of trisubstituted (E)-alphabeta-unsaturated amides in >95% de, that may be subsequently converted into their corresponding (E)-alphabeta-unsaturated acids or (E)-alphabeta-unsaturated oxazolines in good yield. syn-Aldols derived from alphabeta-unsaturated aldehydes gave their corresponding trisubstituted (E)-alphabeta-unsaturated-amides with poorer levels of diastereocontrol, whilst there was a similar loss in (E)-selectivity during elimination of syn-aldols derived from chiral aldehydes. These elimination reactions proceed via rearrangement of the potassium alkoxide of the syn-aldol to a 1,3-oxazinane-2,4-dione enolate intermediate that subsequently eliminates carbon dioxide to afford a trisubstituted (E)-alphabeta-unsaturated amide. The (E)-selectivity observed during the ElcB-type elimination step has been rationalised using a simple conformational model that employs a chair-like transition state to explain the observed stereocontrol.

The stereochemical course of the oxidation of chiral oxazolidinone-substituted enecarbamates has been studied for singlet oxygen (1O2), dimethyldioxirane (DMD), and m-chloroperbenzoic acid (mCPBA) by examining of the special structural and stereoelectronic features of the enecarbamates. Valuable mechanistic insight into these selective oxidations is gained. Whereas the R1 substituent on the chiral auxiliary is responsible for the steric shielding of the double bond and determines the sense of the pi-facial diastereoselectivity, structural characteristic such as the Z/E configuration and the nature of the R 2 group on the double bond are responsible for the extent of the diastereoselectivity. Stereoelectronic steering by the vinylic nitrogen functionality controls the mode selectivity (ene reaction vs [2+2] cycloaddition) in the case of 1O2.

(Matrix presented) A novel alkenylation of enolates using alkenylselenonium salts is described. A reaction of lithium enolates, which were prepared in situ by the reaction of LiHMDS and carbonyl compounds, with alkenylselenonium salts gave the ethenylation products of carbonyl compounds in high yield. Diastereoselective alkenylation was also accomplished by the reaction of the enolates derived from N-acyl-1,3-oxazolidin-2-ones with the alkenylselenonium salt to afford good results (up to 92% yield and up to 95% de).

Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. Synthetic Route of 497-25-6. Introducing a new discovery about 497-25-6, Name is Oxazolidin-2-one

CO2 capture and storage are quite a promising approach to limit greenhouse gas emission. However CO2 capture process relies on the use of amine solutions which are likely to degrade and produce potentially harmful compounds. To ensure an environmental acceptance and to understand this degradation, analytical methods are needed to identify and quantify as many as possible of these products. In our study, monoethanolamine was used as a model compound for CO2 capture. Therefore an analytical strategy was developed to provide the most exhaustive list of degradation products. It was based on the complementarity between liquid and gas chromatography coupled with various mass spectrometry ionization and detection modes.. This analytical strategy enabled the identification of 59 degradation products in pilot plant samples, but 26 of which were never reported. It provides also key information to develop quantification methods for pilot or industrial plant monitoring.
