Enantiodivergent syntheses of (+)- and (?)-1-(2,6-dimethylphenoxy)propan-2-ol: A way to access (+)- and (?)-mexiletine from D-(+)-mannitol

Chiron approach was used to acquire optically pure (R)- and (S)-1-(2,6-dimethylphenoxy)propan-2-ol, immediate precursors of (S)- and (R)-mexiletines, respectively. Two different routes were followed from a D-mannitol-derived optically pure common precursor to get the enantiomeric alcohols separately. Comparison of their specific rotation values with the corresponding literature values as well as exact mirror-image relationship between their CD curves proved their high enantiopurity. These alcohols were then transformed to the corresponding amine-drugs in an efficient one-step process instead of two steps described in the literature.

ACCURATE DETERMINATION OF THE INTRINSIC RACEMIZATION IN CHIRAL SYNTHESIS VIA ENANTIOMER RESOLUTION OF UNDERIVATIZED VICINAL DIOLS

The accurate assessment of the intrinsic racemization (down to 0.01percent), inherent to reactions typically applied in chiral synthesis, demands for (i) a precursor of almost 100percent e.e. (e.g., S-1a, e.e. >=99.99percent), and (ii) a reliable method for the determination of e.e. of the product (e.g., the derivatization-free enantiomer resolution of the vicinal diol 3a by GC on Chirasil-Val).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4254-15-3 is helpful to your research. Reference of 4254-15-3

Catalytic asymmetric chloroamination reaction of alpha,beta-Unsaturated gamma-keto esters and chalcones

Highly efficient catalytic chloroamination reaction of alpha,beta- unsaturated gamma-keto esters and chalcones has been developed via a chloronium-based mechanism to deliver anti-regioselective vicinal chloroamines instead of the aziridinium intermediates delivered aminochlorides. The combination of TsNCl2 and TsNH2 as reagents made the transformation highly efficient, delivering the gamma-carbonyl-beta-chloro- alpha-amino acid derivatives and alpha-chloro-beta-amino-ketone derivatives in nearly quantitative yields with up to 99% ee and 99:1 dr under 0.05-0.5 mol % catalyst loading. TsNHCl was demonstrated to act as the key reactive species to form a bridged chloronium ion intermediate in the presence of a chiral scandium complex. The method might provide useful information for further realization of other haloamination reactions.
