The first enantioselective syntheses of pure R- and S-isoproterenol

An efficient and highly selective synthetic route to either R- or S-isoproterenol (1) is described which employs a robot-like catalytic molecule to establish chirality, and readily provides these important therapeutic agents in enantiomerically pure form.

Chiral Cr(III)-salen complex embedded over sulfonic acid functionalized mesoporous SBA-15 material as an efficient catalyst for the asymmetric Henry reaction

Designing novel catalytic system for efficient synthesis of enantiomerically pure β-hydroxy nitroalkanes is a challenging area of research. Herein, we have designed a chiral heterogeneous catalyst through the successful loading of chiral Cr(III)-salen com

Effect of basic and acidic additives on the separation of some basic drug enantiomers on polysaccharide-based chiral columns with acetonitrile as mobile phase

The separation of enantiomers of 16 basic drugs was studied using polysaccharide-based chiral selectors and acetonitrile as mobile phase with emphasis on the role of basic and acidic additives on the separation and elution order of enantiomers. Out of the studied chiral selectors, amylose phenylcarbamate-based ones more often showed a chiral recognition ability compared to cellulose phenylcarbamate derivatives. An interesting effect was observed with formic acid as additive on enantiomer resolution and enantiomer elution order for some basic drugs. Thus, for instance, the enantioseparation of several β-blockers (atenolol, sotalol, toliprolol) improved not only by the addition of a more conventional basic additive to the mobile phase, but also by the addition of an acidic additive. Moreover, an opposite elution order of enantiomers was observed depending on the nature of the additive (basic or acidic) in the mobile phase.
