Rapid identification of a scalable catalyst for the asymmetric hydrogenation of a sterically demanding aryl enamide

High throughput screening was used to find a cost-effective and scalable catalyst for the asymmetric hydrogenation of a sterically demanding enamide as an intermediate towards a new potent melanocortin receptor agonist useful in the treatment of obesity.

STEREOSELECTIVE PREPARATION OF 4-ARYL PIPERIDINE AMIDES BY ASYMMETRIC HYDROGENATION OF A PROCHIRAL ENAMIDE AND INTERMEDIATES OF THIS PROCESS

The present invention provides an efficient process for the preparation of enentiomerically enriched 4-aryl piperidine amides of structural formula (IV).

An efficient synthesis of a highly functionalized 4-arylpiperidine

In this manuscript, an efficient synthesis of a functionalized 4-arylpiperidine is disclosed. Several synthetic approaches towards formation of the key aryl-piperidine sp3 carbon-carbon bond are discussed, including a scalable route to the piperidine via

Process and intermediates for the preparation of 4-aryl piperidines

A novel process is provided for the preparation of 4-aryl piperidines, and the useful intermediates obtained therein. These compounds are intermediates for the synthesis of melanocortin-4 receptor (MC-4R), which are useful for the treatment of disorders such as obesity, diabetes, male sexual dysfunction, and female sexual dysfunction.

Direct synthesis of 4-arylpiperidines via palladium/copper(I)-cocatalyzed negishi coupling of a 4-piperidylzinc iodide with aromatic halides and triflates

A general procedure for the synthesis of 4-arylpiperidines via the coupling of 4-(N-BOC-piperidyl)zinc iodide with aryl halides and triflates is presented. The reaction requires cocatalysis with both Cl2Pd(dppf) and a copper(I) species. An impr
