Short enantioselective total synthesis of (+)-tofacitinib

An enantioselective total synthesis of Tofacitinib (CP-690,550), a Janus tyrosine kinase (JAK3) specific inhibitor has been achieved from the readily available 4-piperidone. Proline catalysed hydroxylation is the key step for the synthesis of enantiopure 1-benzyl-4-methylpiperidin-3-ol.

η6-Arene CH?O Interaction Directed Dynamic Kinetic Resolution – Asymmetric Transfer Hydrogenation (DKR-ATH) of α-Keto/enol-Lactams

A dynamic kinetic resolution – asymmetric transfer hydrogenation (DKR-ATH) methodology of α-keto/enol-lactams was developed. We also propose a possible catalytic mechanism evolving a transition state stabilized by η6-arene CH?O interaction. The efficient approach can be applied to a wide range of substrates including non-aryl ones which would be difficult to prepare by other asymmetric reduction methods. (Figure presented.).

Method for preparing lactam compound

The invention relates to a preparation method of a lactam compound, and belongs to the field of medicinal chemistry. The preparation method comprises the following steps: carrying out an asymmetric hydrogenation reaction on raw materials under the action of a ruthenium catalyst and a hydrogen donor reagent, and carrying out a post treatment to obtain the target compound. The product obtained by the method is high in ee value, the method is simple and convenient, and the target compound can be easily, conveniently and efficiently obtained.

Asymmetric Synthesis of a Key Intermediate for Tofacitinib via a Dynamic Kinetic Resolution-Reductive Amination Protocol

We report the first example of a catalytic asymmetric reductive amination under dynamic kinetic resolution (DKR) conditions for the preparation of a chiral amine as a key intermediate toward Tofacitinib, an active pharmaceutical ingredient developed by Pfizer. Such a protocol allows the preferential formation of a single product out of four possible diastereomers of the chiral amine starting from the corresponding racemic ketone. The chiral iridium catalyst able to perform such a feast was discovered through a mix of high-throughput screening, racemization study, and reaction optimization.

Formal asymmetric synthesis of (+)-tofacitinib

Tofacitinib is an efficient and selective Janus kinase 3 (JAK3) inhibitor, and is used as an immunosuppressant drug for the treatment of rheumatoid arthritis and transplant patients. Herein we report a concise formal asymmetric synthesis of tofacitinib from homochiral 1,3-dioxolanone 10b, which was elaborated through a highly stereoselective Michael addition followed by solvent-free removal of the chiral auxiliary and ring cyclization to furnish chiral imide 8. The preparation of tofacitinib's precursor 16 could be obtained after reduction of 8 followed by sequential oxidation, reductive amination and SNAr reactions.
