A new facile chemoenzymatic synthesis of levamisole

An efficient and facile chemoenzymatic synthesis of levamisole by employing lipase-mediated resolution of 3-hydroxy-3-phenylpropanenitrile followed by its conversion to β-amino alcohol as the key intermediate is described.

Efficient asymmetric hydrogenation of α-amino ketone derivatives. A highly enantioselective synthesis of phenylephrine, levamisole, carnitine and propranolol

The complexes of pyrrolidine bisphosphine ligands (CPMs) with rhodium (I) were found to be efficient catalysts for asymmetric hydrogenation of α-amino ketone hydrochloride derivatives. Utilizing this methodology, we have developed efficient asymmetric syntheses of the optically active β-amino alcohols, phenylephrine, levamisole, carnitine and propranolol.

The Optical Resolution of 3-(2'-Hydroxy-2'-phenylethyl)-2-thiazolidinimine, and the Crystal Structure of the (2R,3R)-O,O'-Dibenzoyl Hydrogen Tartrate Salt of the (S)-(+)-Enantiomer

The optical resolution has been investigated for 3-(2'-hydroxy-2'-phenylethyl)-2-thiazolidinimine with (2R,3R)-O,O'-dibenzoyltartaric acid.The most effective separation of the enantiomers is attained if the resolution is performed in methanol with the reactants in a 1:1 ratio.The crystal structure at 122 K of the precipitating salt (C11H15N2OS+ * C18H13O-8 * CH3OH) has been determined by X-ray diffraction methods.Crystals are monoclinic, space group P21, with a=7.5831(9), b=12.5698(14), c=15.835(2) Angstroem, β=101.980(9) deg, V=1476.5(3) Angstroem3, Z=2, Dx=1.378 g cm-3, μ=15.00 cm-1.The crystal structure refined to R=0.0255 for 6046 contributing reflections, established that the (+)D rotation of the cation corresponds to the S-enantiomer.The strongest intermolecular interactions are the short hydrogen bonds between the carboxylic acid and the carboxylate groups of anions related by translational symmetry along the a-axis.Methanol also plays a significant role in the hydrogen-bonding system.The packing mode in the present structure is compared to that of the mono-, dibenzoyl- and di-p-toluoyl hydrogen tartrates found in the Cambridge Structural Database.
