In the present paper, the Cu(I)-catalyzed intramolecular aminotrifluoromethylation of O-homoallyl benzimidates with Togni reagent I was reported. O-Homoallyl benzimidates equipped with terminal alkenes produced chiral 1,3-oxazines with high enantioselectivity in the presence of a chiral BOX ligand, and racemic tetrahydro-1,3-oxazepines were obtained in high yields from internal alkene derivatives with a monoprotected amino acid additive under similar conditions.

We report artifactual degradation of pharmaceutical compounds containing primary and secondary amines during peroxy radical-mediated oxidative stress carried out using azoalkane initiators. Two degradation products were detected when model drug compounds dissolved in methanol/water were heated to 40C with radical initiators such as 2,2?-azobis(2-methylpropionitrile) (AIBN). The primary artifact was identified as an alpha-aminonitrile generated from the reaction of the amine group of the model drug with formaldehyde and hydrogen cyanide, generated as byproducts of the stress reaction. A minor artifact was generated from the reaction between the amine group and isocyanic acid, also a byproduct of the stress reaction. We report the effects of pH, initiator/drug molar ratio, and type of azoalkane initiator on the formation of these artifacts. Mass spectrometry and nuclear magnetic resonance were used for structure elucidation, whereas mechanistic studies, including stable isotope labeling experiments, cyanide analysis, and experiments exploring the effects of butylated hydroxyanisole addition, were employed to support the degradation pathways.

Cyanohydrins, prepared in high optical purity from aryl aldehydes, have been converted into alpha-hydroxy aldehydes, alpha-hydroxy ketones and beta-hydroxy amines without any racemization and frequently with good stereoselectivity for the erythro-diastereoisomer (>90percent) at the newly introduced stereogenic centre.

A virtually salt-free and straightforward bimolecular assembly giving N-unsubstituted pyrroles through fully unmasked alpha-amino aldehydes, which was enabled by the dual effects of a catalytic ruthenium complex and an alkali metal base, is reported. Either solvent-free or acceptorless dehydrogenation facilitates high atom, step, and pot economy, which are otherwise difficult to achieve in multistep operations involving protection/deprotection.

We report a general method for the indium-mediated Barbier-type enantioselective allylation of both aromatic and aliphatic aldehydes using commercially available (1S,2R)-(+)-2-amino-1,2-diphenylethanol as a chiral auxiliary. Using only two equivalents of allyl bromide, excellent yields and very good to excellent enantioselectivities are obtained. To our knowledge, the enantioselectivities reported herein are the highest obtained for indium-promoted allylations of carbonyl compounds.

The simple galvanostatic reduction of a solution of MeCN-0.1 M Et 4NPF6 leads to the formation of acetonitrile anion, whose counter-ion is the Et4N+ cation, which leaves the anion ‘naked’. This enhances the reactivity of acetonitrile anion, which reveals to be selective in the N-monoalkylation of bifunctional compounds (cycloserine, beta-amino alcohols, 2-substituted anilines) obtaining high yields. N,N-bis-alkylation has never been observed, indicating that the electrochemical methodology is highly regioselective.

An enantioselective redox-relay oxidative Heck arylation of 1,1-disubstituted alkenes to construct beta-stereocenters was developed using a new pyridyl-oxazoline ligand. Various 1,2-diaryl carbonyl compounds were readily obtained in moderate yield and good to excellent enantioselectivity. Additionally, analysis of the reaction outcomes using multidimensional correlations revealed that enantioselectivity is tied to specific electronic features of the 1,1-disubstituted alkenol and the extent of polarizability of the ligand.

Six new chiral tridentate ditopic ligands with ONO donors possessing different linkers (either achiral or chiral) were synthesized. The characterization of these ligands was accomplished by IR, UV/Vis, NMR, mass spectrometry and optical rotation. These ligands have been treated with a series of metal ions viz., Cu(ii), Cu(i), Co(iii) and Zn(ii), affording varieties of new chiral metal complexes, which have been characterized thoroughly using different analytical and spectroscopic methods. All the complexes were screened for catalytic asymmetric nitroaldol reaction using benzaldehyde as a model substrate. The reaction conditions were optimized and 79% yield with good enantioselectivity (88%) was achieved at RT with the in situ generated catalyst having a piperazine linker and (1R,2S)-2-amino-1,2-diphenylethanol collar in combination with cupric acetate as the metal source. By applying other aromatic and aliphatic aldehydes, similar yields of beta-nitroalcohols with improved enantioselectivities (up to 93%) were achieved. The catalytic system worked very well for up to four cycles with retention of activity and enantioselectivity of beta-nitroalcohols. The Royal Society of Chemistry.
