Pellegata, R.; Dosi, I.; Villa, M.; Lesma, G.; Palmisano, G. published the article 《(-)-β-Pinene as chiral promoter. 2. Stereospecific access to (-)-γ-amino-β(R)-hydroxybutyric acid (GABOB) and (R)-carnitine》. Keywords: carnitine; aminohydroxybutyric acid; pinene chiral promoter; GABOB; stereoselective preparation carnitine.They researched the compound: (R)-Ethyl 4-chloro-3-hydroxybutanoate( cas:90866-33-4 ).COA of Formula: C6H11ClO3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:90866-33-4) here.
Treating (-)-β-pinene (I) with RCHO (R = Cl3C, EtO2C) and FeCl3 gave 60-75% the ene adducts II. A stereochem. correlation between II and their products of alk. hydrolysis is reported. Starting from II (R = Cl3C), by using a degradative sequence, a stereocontrolled approach to (R)-γ-amino-β-hydroxybutyric acid and (R)-carnitine-HCl is described.
Here is just a brief introduction to this compound(90866-33-4)COA of Formula: C6H11ClO3, more information about the compound((R)-Ethyl 4-chloro-3-hydroxybutanoate) is in the article, you can click the link below.
