Eliglustat is a ceramide glucosyltransferase inhibitor work as first line oral therapy for adults with Gaucher disease type 1 (a rare disease) at present. Although the eliglustat in enantiomerically pure forms is obtained by asymmetric syntheses, the reported methods suffer from many limits when it comes to industrial applications. Therefore, the preparation of a racemic mixture followed by resolution can still be a viable and straightforward alternative, especially when it could be adapted to large scale. Herein, we developed an effective and practical synthetic route to prepare stereoisomers mixture of eliglustat, and a novel chiral resolution method to prepare eliglustat. Using 1,1'-Binaphthyl-2,2'-diyl -hydrogenphosphate (BNDHP) as resolution reagent, optical pure eliglustat (e.e. >99%, 13.97% total yield) could be obtained after recrystallization.

The α-helix is an abundant and functionally important element of protein secondary structure, which has motivated intensive efforts toward chemical strategies to stabilize helical folds. One such method is the incorporation of non-canonical backbone composition through an additional methyl substituent at the Cα atom. Examples of monomers include the achiral 2-aminoisobutyric acid (Aib) with geminal dimethyl substitution and chiral analogues with one methyl and one non-methyl substituent.

Asymmetric Synthesis of Azahelicenes via CPA-Catalyzed Kinetic Resolution.

Org Lett

January 2025

Key Laboratory of Organic Synthesis of Jiangsu Province, College of Chemistry, Chemical Engineering and Materials Science & Collaborative Innovation Center of Suzhou Nano Science and Technology, Soochow University, Suzhou 215123, P. R. China.

The azahelicenes are structurally fascinating and practically useful chiral scaffolds, but their synthesis, especially in a catalytically asymmetric manner, is rather challenging. Herein, we report a CPA-catalyzed transfer hydrogenation process, which enables a rapid kinetic resolution of aza[6]helicenes. The established strategy provides facile access to enantioenriched aza[6]helicenes and tetrahydro[6]helicenes from easily available starting materials.

Atomically precise nanoclusters can be assembled into ordered superlattices with unique electronic, magnetic, optical and catalytic properties. The co-crystallization of nanoclusters with functional organic molecules provides opportunities to access an even wider range of structures and properties, but can be challenging to control synthetically. Here we introduce a supramolecular approach to direct the assembly of atomically precise silver nanoclusters into a series of nanocluster‒organic ionic co-crystals with tunable structures and properties.

Chirality, a basic property of symmetry breaking, is crucial for fields such as biology and physics. Recent advances in the study of chiral systems have stimulated interest in the discovery of symmetry-breaking states that enable exotic phenomena such as spontaneous gyrotropic order and superconductivity. Here we examine the interaction between light chirality and electron spins in indium selenide and study the effect of magnetic field on emerging tunnelling photocurrents at the Van Hove singularity.

Study on Preparation Process of Anticoagulant BAY2433334.

Molecules

December 2024

Chengdu Shibeikang Biomedical Technlogy Co., Ltd., 26-1-2, No.2 Tianyu Road, Chendu Gaoxin West District, Chengdu 611700, China.

A new process route suitable for the industrial production of BAY2433334 has been developed in this paper, which avoids the patent limitations of the originator company of BAY2433334 to the preparation of BAY2433334. BAY2433334 is obtained from (2)-2-aminobutyric acid by esterification, diazotization, condensation reactions, deacetyl deprotection, activation reactions, and Mitsunobu reactions. This method is simple to operate, and the raw materials are inexpensive and readily available.
