First enantiopure calix[6]aza-cryptand: Synthesis and chiral recognition properties towards neutral molecules

The synthesis of the first enantiopure calix[6]aza-cryptand was achieved in five steps from the known 1,3,5-tris-O-methylated calix[6]arene. A 1H NMR spectroscopic study has shown that the chiral tren cap constrains the calixarene core in a straight cone conformation ideal for host-guest chemistry applications. As a result, the tetra-protonated derivative displays remarkable host properties towards polar neutral molecules and enantioselective recognition processes have been evidenced with chiral guests.

Fine-tuning monophosphine ligands for enhanced enantioselectivity. Influence of chiral hemilabile pendant groups

C2-Symmetric P-(2-X-aryl)-2,5-dialkylphospholanes (X = dioxolan-2-yl or dioxan-2-yl), designed on the basis of a working model for asymmetric induction, are effective ligands for the Ni(II)-catalyzed asymmetric hydrovinylation of styrenes. Excellent yields (>99%), selectivities for the desired 3-arylbutenes (>99%), high S/C ratios (>1200), and ee’s (up to 91%) have been realized for a number of prototypical vinylarenes. In the dioxolane series, the selectivity depends on the configuration of the C 4 and C5 carbons.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about19132-06-0.Product Details of 19132-06-0

Synthesis and chiral recognition properties of two novel chiral calix[4]arene tartaric ester derivatives

Two new chiral calix[4]arene derivatives containing tartaric acid ester moieties were synthesized. The chiral calix[4]arenes are in a ‘cone’ conformation according to NMR spectroscopy. The chiral recognition capabilities of 1-4 toward the guests, 1,2-propanediol and serine methyl ester hydrochloride (SerOMe), were investigated (1H NMR spectroscopy).

Enantiomeric Interactions and Reaction Rates: Ketalization of (S)- and (RS)-1,2-Propanediols

Aliphatic ketones, e.g., butanone, are converted nearly quantitatively to the corresponding dioxolanes (ketals) in neat (S)- or (RS)-1,2-propanediol containing dichloroacetic acid.The reactions follow the pseudo-first-order law at a given acid concentration, are inhibited by water, and proceed approximately twofold faster in (RS)-diol-O,O-d2 than in undeuterated diol.No difference in rates greater than 1percent could be detected between (S)- and (RS)-diols at identical temperatures, acid concentrations, and water concentrations.Thus, for a chiral diol molecule and the activated complex, free-energy differences are virtually the same in (S)- and (RS)-diols as solvents.Differences in interactions among identical and enantiomeric molecules, if any, are evidently matched by differences in the activated complexes.

A comparative study of the relative stability of representative chiral and achiral boronic esters employing transesterification

A comparative study of the transesterification of five representative chiral and achiral boronic esters with various structurally modified diols was undertaken to qualitatively understand the factors influencing the relative stability of these boronic esters. Several factors such as chelation, conformation, steric bulk of the substituents, size of the heterocycle, and entropy influence the relative rate of transesterification as well as the stability of the boronic esters. Amongst these boronic esters, pinanediol phenylboronic ester was found to be the most stable boronic ester whereas DIPT boronic ester appeared to be thermodynamically the least stable one. The transesterification with sterically hindered diols was observed to be relatively slow, but afforded thermodynamically more stable boronic esters. Boronic esters derived from cis-cyclopentanediols and the bicyclo[2.2.1]heptane-exo,exo-2,3- diols are relatively more stable. This study not only presents the qualitative picture of relative stability of various boronic esters, but also provides helpful hints regarding the possible recovery of chiral auxiliaries. Many C 2-symmetric chiral auxiliaries, such as 2,3-butanediol, 2,4-pentanediol, DIPT, and cis-cyclohexane-1,2-diol, can be retrieved by simple transesterification of the corresponding boronic esters with commercial inexpensive diols, such as pinacol, 1,3-propanediol, and neopentyl glycol.

Synthesis and antibacterial and antifungal evaluation of some chalcone based sulfones and bisulfones

Two series of chalcone based sulfone and bisulfone derivatives were synthesized using chalcone, thiophenol and sodium metal at room temperature, followed by oxidation of chalcone sulfides with m-CPBA at 0 C in a novel method. Both sulfones and bisulfones were evaluated for their antimicrobial activities against Aspergillus niger and Candida albicans (yeast), Bacillus subtilis and Staphylococcus aureus (Gram (+) bacteria) and Pseudomonas aeruginosa and Salmonella typhimurium (Gram (-) bacteria) strains. Among them, compounds 2c, 3c, 6c, 7c, 8c and 9c have shown high antifungal activity against C. albicans compare to reference drugs viz. Amphotericin-B and Nystatin. Compound 1c has shown slightly better antibacterial activity against B. subtilis and compounds 5c, 6c and 7c have shown excellent antibacterial activity against S. typhimurium in compare to reference drugs Ampicillin and Kanamycin.
