Chiral bis(oxazoline)copper(II) complexes as lewis acid catalysts for the enantioselective Diels-Alder reaction

Bis(oxazoline)copper(II) complexes are highly enantioselective catalysts in Diels-Alder reactions involving bidentate dienophiles. Cationic [Cu((S,S)- t-Bu-box)]X2 complexes with different counterions have been used as catalysts, revealing a profound influence of the counterion on the rate and stereoselectivity of the catalyst. A square-planar catalyst-substrate complex is proposed to account for the high diastereo- and enantioselectivities observed. Three bis(oxazoline)-Cu(II) X-ray structures have been obtained that support this model. Double-stereodifferentiating experiments, performed employing chiral dienophiles, afforded results that are fully consistent with the proposed square-planar transition-state assemblage. In addition to imide- based substrates, alpha,beta-unsaturated thiazolidine-2-thiones have been introduced as a new class of dienophiles with enhanced reactivity. Kinetics experiments were performed to quantify the role that product inhibition plays in the course of the reaction. Rate and equilibrium binding constants of various catalyst inhibitors were also derived from the kinetic analysis. A comparative study was undertaken to elucidate the differences between the bis(oxazoline)-Cu(II) catalyst and the bis(oxazoline) catalysts derived from Fe(III), Mg(II), and Zn(II). Catalyst performance was found to be a function of a subtle relationship between bis(oxazoline) structure and transition metal.

New bis-chelated and di-cyclopentadienyl titanium(IV) derivatives of mono-, di- and tri-chloroacetic acids have been prepared from the respective dichlorotitanium compounds and sodium salts of chloroacetic acids.In the bis-chelated titanium dichloroacetates, the acetate groups act as unidentate moieties with chelating ligands remaining coordinated to titanium thereby retaining their octahedral-geometry.No evidence for the association of the molecule has been obtained.In the di-cyclopentadienyl derivaties, the acetate groups coordinate to titanium, showing their bidentate nature.

Nanocrystals: A perspective on translational research and clinical studies

Poorly soluble small molecules typically pose translational hurdles owing to their low solubility, low bioavailability, and formulation challenges. Nanocrystallization is a versatile method for salvaging poorly soluble drugs with the added benefit of a carrier-free delivery system. In this review, we provide a comprehensive analysis of nanocrystals with emphasis on their clinical translation. Additionally, the review sheds light on clinically approved nanocrystal drug products as well as those in development.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride, you can also check out more blogs about122-18-9

Development of new HPLC chiral stationary phases based on native and derivatized cyclofructans

An unusual class of chiral selectors, cyclofructans, is introduced for the first time as bonded chiral stationary phases. Compared to native cyclofructans (CFs), which have rather limited capabilities as chiral selectors, aliphatic-and aromatic-functionalized CF6s possess unique and very different enantiomeric selectivities. Indeed, they are shown to separate a very broad range of racemic compounds. In particular, aliphatic-derivatized CF6s with a low substitution degree baseline separate all tested chiral primary amines. It appears that partial derivatization on the CF6 molecule disrupts the molecular internal hydrogen bonding, thereby making the core of the molecule more accessible. In contrast, highly aromaticfunctionalized CF6 stationary phases lose most of the enantioselective capabilities toward primary amines, however they gain broad selectivity for most other types of analytes. This class of stationary phases also demonstrates high “loadability” and therefore has great potential for preparative separations. The variations in enantiomeric selectivity often can be correlated with distinct structural features of the selector. The separations occur predominantly in the presence of organic solvents.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Enantioselective total synthesis of pyrrolo-[2,1-: C] [1,4]-benzodiazepine monomers (S)-(-)-barmumycin and (S)-(+)-boseongazepine B

An efficient enantioselective total synthesis of pyrrolo-[2,1-c][1,4]benzodiazepine (PBD) monomers (S)-(-)-barmumycin and (S)-(+)-boseongazepine B and collective formal total syntheses of oxoprothracarcin, prothracarcin and (S)-(+)-boseongazepine C are described. The present approach is based on an efficient construction of an ethylidene substituted C-4 pyrrolidine core, that is the stereocontrolled introduction of a trisubstituted double bond through simple enolate alpha-alkylation of an ester, which also relies on a proline catalysed asymmetric alpha-amination followed by HWE olefination. The present synthetic route possesses superior stereocontrol over the C-4 ethylidene substituent as well as the C-(S) stereogenic center, which allows more functional variations on the five-membered prolinol core as compared to the existing PBD synthesis.
