A aliskiren or its salt separation and analysis method

The invention relates to a separation analysis method using polysaccharide derivative-bonded and coated silica as a stationary phase and an organic solvent as a mobile phase for separation analysis of aliskiren and isomers thereof, effective separation of the aliskiren and isomers thereof can be realized, and the separation analysis method has the important meaning to the product quality control.

Formal total synthesis of aliskiren

The efficient and selective formal total synthesis of aliskiren is described. Aliskiren, a renin inhibitor drug, has received considerable attention, primarily because it is the first of the renin inhibitor drugs to be approved by the FDA. Herein, the formal synthesis of aliskiren by iridium-catalyzed asymmetric hydrogenation of two allylic alcohol fragments is reported. Screening a number of N,P-ligated iridium catalysts yielded two catalysts that gave the highest enantioselectivity in the hydrogenation, which gave the saturated alcohols in 97 and 93 % ee. In only four steps after hydrogenation, the fragments were combined by using the Julia-Kocienski reaction to produce late-stage intermediate in an overall yield of 18 %.

A new approach to the synthesis of peptidomimetic renin inhibitors: Palladium-catalyzed asymmetric allylation of acyclic alkyl aryl ketones

A new approach to the synthesis of Tekturna, a recently marketed drug for hypertension, takes advantage of a modified protocol of the Stoltz palladium-catalyzed asymmetric allylation with a t-BuPHOX ligand for the synthesis of allylated acyclic alkyl aryl
