Atorvastatin Derived HMG-CoA Reductase Degradation Inducing Compound

The present invention relates to a HMG-CoA reductase degradation-inducing compound and, more specifically, to a bifunctional compound in which atorvastatin and E3 ubiquitin ligase binding moiety are chemically linked as HMG-CoA reductase binding moiety, to a production method thereof, to a HMG-CoA reductase degradation method using the same, and to a pharmaceutical composition for preventing or treating HMG-CoA reductase-related diseases, comprising the same.

Process for the synthesis of (4R-cis)-1,1-dimethylethyl 6-cyanomethyl-2,2-dimethyl-1,3-dioxane-4-acetate

An improved process for the preparation of (4R-cis)-1,1-dimethylethyl 6-cyanomethyl-2,2-dimethyl-1,3-dioxane-4-acetate is described where a hydroxy ester derivative is converted in two steps to the desired product, as well as valuable intermediates used in the process.

Process for the synthesis of (5R)-1,1-dimethylethyl-6-cyano-5-hydroxy-3-oxo-hexanoate

An improved process for the preparation of (5R)-1,1-dimethylethyl-6-cyano-5-hydroxy-3-oxo-hexanoate is described where a halo hydroxyester or other activated dihydroxyester is converted in two steps to the desired product.

Process for trans-6-(2-(substituted-pyrrol-1-yl)alkyl)pryan-2-one inhibitors of cholesterol synthesis

An improved process for the preparation of trans-6-[2-(substituted-pyrrol-1-yl)alkyl]pyran-2-ones by a novel synthesis is described where 1,6-heptadien-4-ol is converted in eight operations to the desired products, as well as an improved process for the preparation of (2R-trans) and trans-(±)-5-(4-fluorophenyl)-2-(1-methylethyl)-N-4-diphenyl-1-[2-tetrahydro-4-hydroxy-6-oxo-2H-pyran-2-yl)ethyl]-1H-pyrrole-3-carboxamide by a novel synthesis where 4-methyl-3-oxo-N-phenylpentanamide is converted in eight operations to the desired product or alternatively 4-fluoro-α-[2-methyl-1-oxopropyl]-γ-oxo-N,β-diphenylbenzenebutaneamide is converted in one step to the desired product, and additionally, a process for preparing (2R-trans)-5-(4-fluorophenyl)-2-(1-methylethyl)-N,4-diphenyl-1-[2-(tetrahydro-4-hydroxy-6-oxo-2H-pyran-2-yl)ethyl]-1H-pyrrole-3-carboxamide from (R)-4-cyano-3-[[(1,1-dimethylethyl)dimethylsilyl]oxy]butanoic acid, as well as other valuable intermediates used in the processes.
