Exploitation of the enantioselectivity space of coated amylose tris(3,5-dimethylphenylcarbamate) in mixtures of 2-propanol and acetonitrile.

Chiral stationary phases (CSPs) with coated amylose tris(3,5-dimethylphenylcarbamate) (ADMPC) selector have long been recognized for their excellent chiral recognition ability in liquid chromatography. The conformational versatility behind this feature is the source of their known hysteretic behavior, which has been previously observed in polar organic (PO) mode eluents containing 2-propanol (IPA). Mixtures of IPA and acetonitrile (MeCN), a typical PO mode eluent system, have not been examined in this aspect yet, even though hysteresis is promising for finding unique unexplored enantioselectivities.

Maternal Periodontal Status as a Factor Influencing Obstetrical Outcomes.

Preterm birth as a complex phenomenon is influenced by numerous endogenic and exogenic factors, although its exact cause often remains obscure. According to epidemiological studies, maternal periodontal diseases, in addition to affecting general health, can also cause adverse pregnancy outcomes. Nonetheless, the existing results in the literature regarding this topic remain controversial.

A protocol to replace dedication to either normal phase or polar organic mode for chiral stationary phases containing amylose tris(3,5-dimethylphenylcarbamate).

Alteration of the enantiorecognition ability of polysaccharide-based chiral columns in the shipping normal phase (NP) eluent after exposition to polar organic (PO) mode eluents can be conceived as an incomplete hysteresis cycle. Non-standard solvents provide a solution to overcome this issue with immobilized stationary phases, but a procedure was missing so far to regenerate coated stationary phases from the altered state. Recent results with alcohol mixtures within the PO mode showed that an appropriate order of standard solvents may also be suitable to complete hysteresis.

Experimental and computational study of BF-catalyzed transformations of -(pivaloylaminomethyl)benzaldehydes: an unexpected difference from TFA catalysis.

Previously, we have studied the trifluoroacetic acid (TFA)-catalyzed rearrangements of unsubstituted and alkoxy-substituted -(pivaloylaminomethyl)benzaldehydes and revealed the formation of rearranged, regioisomeric aldehydes along with dimer-like products ("TFA dimers"). In the present study, related reactions of -(pivaloylaminomethyl)benzaldehydes are described with the difference that boron trifluoride diethyl etherate (BF·OEt) is used as the catalyst. Although in these reactions the formation of the same "TFA dimers" can be observed after a couple of hours reaction time, during further stirring these are transformed into a new dimer-like keto compound ("BF dimer") that gradually becomes the main product.

The personalized Berger method is usable to solve the problem of tibial rotation.

Utilization of the hysteresis phenomenon for chiral high-performance liquid chromatographic method selection in polar organic mode.

Polysaccharide-based chiral stationary phases (CSPs) are outstandingly suitable to play a key role in chiral HPLC method selection strategies, since they provide high success rates. One reason for this ability is that they adopt a diversity of higher order structures in various eluents, resulting in versatile chiral environments. A potential to extend this versatility further was expected and examined in the present study, based on the recently discovered hysteretic behavior of a widely used chiral selector (CS), amylose tris(3,5-dimethylphenylcarbamate).
