The asymmetric hydrogenation of a selectively crystallised (E)-4,4-diaryl-3-butenoate with a rhodium-PhanePhos catalyst is described, providing an intermediate to the antidepressant sertraline.
A step-wise reduction of nonracemic α-ketoamides to α-methine amides under mild conditions

A step-wise reductive method that converts nonracemic γ-chiral α-ketoamides into amide derivatives was developed under mild conditions. The method involves a highly efficient three-step transformation including NaBH4-reduction, bromination and Pd/C hydrogenation reactions. As a consequence, a variety of nonracemic γ-diaryl amides products were obtained in high overall yields with excellent enantiomeric specificity. The utility of the method is demonstrated through the concise formal synthesis of (+)-sertraline in good overall yield.

The first example of copper-catalyzed ring-opening, enantioselective arylation of cyclic ketoxime esters to access ω,ω-diaryl alkyl nitriles has been developed in high yield (up to 92% yield) with excellent enantioselectivity (up to 91% ee). Side-arm bis(oxazoline) ligand plays a significant role in this asymmetric catalytic transformation, which provides an efficient route to construct diverse chiral ω,ω-diaryl alkyl nitriles. Synthetic utility has also been demonstrated in the further derivatization of the ω,ω-diaryl alkyl nitrile to the corresponding amide.

The marine transaminase, P-ω-TA, can be employed for the transamination from 1-aminotetralins and 1-aminoindanes with differentiation of stereochemistry at both the site of reaction and at a remote stereocentre resulting in formation of ketone products with up to 93% ee. While 4-substituents are tolerated on the tetralin core, the presence of 3- or 8-substituents is not tolerated by the transaminase. In general P-ω-TA shows capacity for remote diastereoselectivity, although both the stereoselectivity and efficiency are dependent on the specific substrate structure. Optimum efficiency and selectivity are seen with 4-haloaryl-1-aminotetralins and 3-haloaryl-1-aminoindanes, which may be associated with the marine origin of this enzyme. This journal is
Chemoenzymatic Synthesis of Sertraline
Marx, Lisa,Ríos-Lombardía, Nicolás,Süss, Philipp,H?hne, Matthias,Morís, Francisco,González-Sabín, Javier,Berglund, Per

A chemoenzymatic approach has been developed for the preparation of sertraline, an established anti-depressant drug. Ketoreductases (KREDs) were employed to yield a key chiral precursor. The bioreduction of the racemic tetralone exhibited excellent enantioselectivity (>99 % ee) and diastereomeric ratio (99:1) at 29 % conversion (the maximum theoretical yield is 50 %) after 7 hours. The resulting (S,S)-alcohol was efficiently oxidized to an enantiopure (S)-ketone, an immediate precursor of sertraline, by using sodium hypochlorite as oxidant and 2-azaadamantane N-oxyl (AZADO) as organocatalyst. Alternative routes aiming at the direct biocatalytic amination using imine reductases and transaminases were unsuccessful.

Evaluation of an esterase annotated as 26D isolated from a marine metagenomic library is described. Esterase 26D was found to have a unique substrate scope, including synthetic transformations which could not be readily effected in a synthetically useful manner using commercially available enzymes. Esterase 26D was more selective towards substrates which had larger, more sterically demanding substituents (i. e. iso-propyl or tert-butyl groups) on the β-carbon, which is in contrast to previously tested commercially available enzymes which displayed a preference for substrates with sterically less demanding substituents (e.g. methyl group) at the β-carbon. (Figure presented.).
Correction to: Nickel-catalyzed asymmetric reductive cross-coupling to access 1,1-diarylalkanes (Journal of the American Chemical Society (2017) 139 (5684-5687) DOI: 10.1021/jacs.7b01705)

Pages 5684 and 5685, Table of Contents, and Supporting Information. The stereochemistry of L1, depicted as the (S,S)- enantiomer in Figure 1, Table 1, the TOC graphic (identical to Figure 1), and the Supporting Information of the original publication, was incorrect. (R,R)-L1 was used in this study. The stereochemistry of (R,R)-L1 has been confirmed by singlecrystal X-ray diffraction; the X-ray diffraction data and CIF file for (R,R)-L1 have been added to the Supporting Information. The corrected TOC graphic/Figure 1 is shown here. (R,R)-L4 and (R,R)-L5 were also used in Table 1 and incorrectly depicted as (S,S)-L4 and (S,S)-L5 in the original publication. To reflect that different enantiomeric series of catalysts were used, Table 1 has been updated to indicate that entries 2, 3, and 6 produce (S)-3a. This correction does not change the stereochemical assignment of the diarylalkane products, or the conclusions of the Communication. The stereochemistry of the products was assigned by obtaining an X-ray structure of diarylalkane 3k, and the rest of the compounds were assigned by analogy. (Table Presented).

An asymmetric Ni-catalyzed reductive cross-coupling of (hetero)aryl iodides and benzylic chlorides has been developed to prepare enantioenriched 1,1-diarylalkanes. As part of these studies, a new chiral bioxazoline ligand, 4-heptyl-BiOX (L1), was developed in order to obtain products in synthetically useful yield and enantioselectivity. The reaction tolerates a variety of heterocyclic coupling partners, including pyridines, pyrimidines, indoles, and piperidines.

A highly regio- and enantioselective rhodium-catalyzed 1,4-addition of arylboronic acids to β,γ-unsaturated α-ketoamides using a simple new chiral sulfinylphosphine ligand is described. This transformation provides an attractive approach to construct chiral nonracemic γ,γ-diarylsubstituted carbonyl compounds, as exemplified in the concise syntheses of sertraline and tetrahydroquinoline-2-carboxylamide. Constructing chiral carbonyls: A simple new chiral sulfinylphosphine ligand L was developed, which promoted excellent 1,4-selectivities and enantioselectivities in the rhodium-catalyzed conjugate addition of arylboronic acids to β,γ-unsaturated α-ketoamides. The desired γ,γ-diaryl-α-ketocarbonyl compounds were afforded with high yields and high optical purities.
