Compounds which are useful as inhibitors of cholesterol biosynthesis and thus as hypocholesterolemic agents are provided which have a quinoline or a pyridine anchor attached by means of a linker to a binding domain sidechain, which compounds inhibit the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase.
本研究提供了可作为胆固醇生物合成抑制剂从而作为低胆固醇血症药物的化合物,这些化合物具有一个喹啉或吡啶锚,通过连接物与结合域侧链相连,这些化合物可抑制 3-羟基-3-甲基戊二酰辅酶 A 还原酶。

chemoenzymatic Dynamic Kinetic Resolution (DKR) of unsymmetrical benzoins (Ar1≠Ar2) has been carried out, by using Pseudomonas stutzeri lipase stereorecognition pattern. After studying this lipase behaviour, a high preference towards acylation of those benzoins containing substituents in the phenyl ring rather than in the benzoyl moiety was observed. This fact allowed the development of the DKR process of this

The asymmetric alkylation of acyclic ketones is a longstanding challenge in organic synthesis. Reported herein are diastereoselective and enantioselective allylic substitutions with acyclic α‐alkoxy ketones catalyzed by a metallacyclic iridium complex to form products with contiguous stereogenic centers derived from the nucleophile and electrophile. These reactions occur between allyl methyl carbonates
