The present invention relates to an improved process for the preparation of N-((1R,2R)-1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-1-hydroxy-3-(pyrrolidin-1-yl)propan-2-yl)octanamide (A), which is known as ELIGLUSTAT and its pharmaceutically acceptable salts, comprising the formation of novel intermediate metal complex (III), which on hydrolysis in presence of acid provides amine compound (IV) (as described herein), which is treated with pyrrolidine and subsequently reduced to convert into Eliglustat (A).

Metal ion-directed carboxylic acid functionalized polyoxometalate hybrid compounds, and their preparation method and applications in catalyzing the degradation of chemical warfare agent simulants. In the synthesis, Na.sub.2MoO.sub.4, p-hydroxybenzonic acid (PHBA), alanine (Ala), KCl, transition metal cations and As.sub.2O.sub.3 as raw materials and water are used as solvent. At room temperature, 2-chloroethyl ethyl sulfide (CEES) and the prepared polyoxometalate hybrid compounds were mixed together in anhydrous ethanol and stirred, and H.sub.2O.sub.2 was subsequently added into the reaction system. The catalytic reaction for the degradation of CEES was finished within 5 min under stirring. In the catalytic hydrolysis of diethyl cyanophosphonate (DECP), the catalyst, DECP, DMF and H.sub.2O were put together and mixed fully. The prepared polyoxometalate hybrid compounds have the advantages of high conversion, high selectivity and easy recyclability in catalyzing the degradation of two types of chemical warfare agent simulant.

Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N′-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

The dihydric alcohol has heterocyclic structures. The isocyanate solution and the dihydric alcohol solution are mixed, causing the isocyanate and the dihydric alcohol polymerize to form a polymer precursor. The polymer precursor includes a hard segment and a soft segment. The hard segment includes urethane groups, the soft segment includes heterocyclic structures. The polymer precursor and the metal salt solution are mixed, causing the heterocyclic structures and metal ions to undergo a chelation reaction to form a coordination complex, thereby forming the self-healing composition. A self-healing composition prepared by the method, and self-healing film using the self-healing composition are also disclosed.
