Synthesis and characterization of both enantiomers of a chiral C60 derivative with C2 symmetry

The addition of chiral diamines to C60 allows the synthesis of the two enantiomers of a chiral C60 derivative with C2 symmetry. The circular dichroism spectra of the two isomers show a very intense chirospectroscopic response.

The role of chelating diamine ligands in the Goldberg reaction: A kinetic study on the copper-catalyzed amidation of aryl iodides

The mechanistic details of the Cu-catalyzed amidation of aryl iodides are presented. The kinetic data suggest that the diamine ligand prevents multiple ligation of the amide. The formation of an amidocuprate species external to the catalytic cycle helped to rationalize the dependence on diamine concentration and the inverse dependence on amide concentration at low diamine concentrations. The intermediacy of a Cu(I) amidate was established through both its chemical and kinetic competency. Copyright

Method for synthesizing trans-cyclohexanedimethanamine

The invention discloses a method for synthesizing trans-cyclohexanedimethanamine, comprising steps of reacting cyclohexene oxide and methylamine aqueous solution under the catalysis of boric acid, and then adding sulfuric acid, dewatering to form an ester, ring-closing under alkaline conditions, adding methylamine aqueous solution and boric acid for hermetic reaction, and distilling to obtain trans-cyclohexanedimethanamine. The synthetic process is simple to perform, provides facilitated isolation and purification and high yield and product purity, and is suitable for batch production.

GLYCINE TRANSPORTER INHIBITOR

The present invention provides novel compounds of formula [IA] or pharmaceutically acceptable salts thereof: which are useful in the prevention or treatment of diseases such as schizophrenia, Alzheimer's disease, cognitive impairment, dementia, anxiety disorders (e.g., generalized anxiety disorder, panic disorder, obsessive-compulsive disorder, social anxiety disorder, post-traumatic stress disorder, specific phobias, acute stress disorder), depression, drug dependence, spasm, tremor, pain, Parkinson's disease, attention deficit hyperactivity disorder, bipolar disorder, eating disorder, or sleep disorders, which is based on the glycine uptake-inhibiting action.

An efficient synthesis of enantiomerically pure trans-N1,N 2-dimethylcyclohexane-1,2-diamine

A new pathway is described to produce a highly optically pure isomer of trans-N1,N2-dimethylcyclohexane-1,2-diamine through four simple steps. Reaction of cyclohexene oxide with aqueous methylamine, followed by cyclisation with Mitsunobu reagent and ring-opening reactions gave rac-trans-N1,N2-dimethylcyclohexane-1,2-diamine, and the enantiomers were obtained via a kinetic resolution using tartaric acid.

On the two-ligand catalytic asymmetric deprotonation of N-Boc pyrrolidine: Probing the effect of the stoichiometric ligand

(Chemical Equation Presented) To map out the stoichiometric ligand requirements in the two-ligand catalytic asymmetric deprotonation of N-Boc pyrrolidine, 24 different ligands have been evaluated; the highest enantioselectivity (90:10 er) was obtained by using s-BuLi in the presence of 0.3 equiv of (-)-sparteine and 1.3 equiv of a cyclohexanediamine-derived ligand.

The copper-catalyzed N-arylation of indoles

A general method for the N-arylation of indoles using catalysts derived from Cul and trans-1,2-cyclohexanediamine (1a), trans-N,N′-dimethyl-1,2-cyclohexanediamine (2a), or N,N′-dimethyl-ethylenediamine (3) is reported. N-Arylindoles can be produced in high yield from the coupling of an aryl iodide or aryl bromide with a variety of indoles.

The asymmetric synthesis of α-substituted α-methyl and α-phenyl phosphonic acids: Design, carbanion geometry, reactivity and preparative aspects of chiral alkyl bicyclic phosphonamides

The design, preparation, structural and spectroscopic analyses of topologically unique and enantiomerically pure alkyl phosphonamides are described. In the case of α-ethyl and α-benzyl phosphonamides, the geometry of both the secondary and tertiary carbanions was determined to be planar through deprotonation/deuteration/alkylation experiments. Stereoselective alkylations of such systems proceeded in good yields and with high diastereoselectivities. The resulting α,α-alkylated phosphonamides were hydrolyzed to give the corresponding α,α-alkyl phosphonic acids with high degrees of enantiomeric purity.

Cosmetic composition containing an amide-amine type condensate, and a cosmetic treating process using said condensate

A cosmetic composition for improving the suppleness of the skin or hair and for protecting the keratin of the skin or hair from degradation by atmospheric agents or light comprises in a cosmetic or dermatologic acceptable vehicle a saturated condensate resulting from the polyaddition of a bis-acrylamide and a sterically hindered primary diamine, the condensate being saturated by hydrogenation or by addition of a thiol or an amine on the double bonds of the acrylamide residue.

211. Scope and Limitations of the Reductive Coupling of Aromatic Aldimine Derivatives with Formation of 1,2-Diarylethylenediamine Units, Using Low-Valent Titanium Reagents

Besides the adducts from lithium amides to aromatic aldehydes, iminium salts, aminals, and N-silylimines of aromatic aldehydes are coupled by the black suspension obtained from TiCl4 and Mg turnings in tetrahydrofuran (THF).The 1,2-diarylethylenediamines with tertiary and primary amino groups thus obtained are formed with no or only moderate diastereoselectivity (products 4a-d (Scheme 2) and 5a-e (Scheme 3), respectively); the amine component may contain a strained ring or additional heteroatoms as in azetidin, bis(2-metoxyethyl)amine piperazine, morpholine, and thiomorpholine (products 6a-e; Table 1).By an in-situ procedure, ethylenediamines and propane-1,3-diamines with two secondary amino groups are cyclized with aromatic aldehydes to give exclusively trans-diaryl-substituted piperazine and perhydro-1,4-diazepine derivatives (products 7a-f; Table 2).Enantiomerically pure monocyclic trans,cis-5-alkyl-2,3-diaryl-piperazines and diazabicyclononanes and -decanes are obtained by employing suitable diamines prepared from the amino acids (S)-alanine, (S)-phenylalanine, (S)-proline, and from (S,S)- or (R,R)-cyclohexane-1,2-diamine, respectively (products 11a-i, 7e; Table 4).The configurations of all products are derived from the high-field NMR spectra, some of which are discussed in detail (Figs. 1 and 2, Tables 3 and 5); all new compounds are fully characterized by their physical data.Depending upon the structure of the components employed, the yields of purified products range from as low as 7percent to essentially quantitative.
