Calvisi, Giuseppina; Catini, Roberto; Chiariotti, Wilma; Giannessi, Fabio; Muck, Sandra; Tinti, Maria Ornella; De Angelis, Francesco published the article 《Single-step conversion of chiral carnitine and derivatives into (S)- and (R)-β-substituted γ-butyrolactones》. Keywords: butyrolactone preparation; carnitine cyclocondensation.They researched the compound: (R)-4-Hydroxydihydrofuran-2(3H)-one( cas:58081-05-3 ).HPLC of Formula: 58081-05-3. 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:58081-05-3) here.
An efficient 1-step conversion of chiral carnitine and its derivatives into stereoisomerically pure (S)- and (R)-β-substituted γ-butyrolactones by cyclocondensation is described. (S)- or (R)-carnitine and (R)-aminocarnitine give β-hydroxy-γ-butyrolactone and β-amino-γ-butyrolactone in 82 and 77% yield, resp., with retention. (R)-(acetylamino)carnitine gives (R)-β-acetylamino-γ-butyrolactone in 90% yield, while (R)-acetylcarnitine gives 2(5H)-furanone under the same reaction conditions in 77% yield via cyclization and subsequent elimination. (R)-N-benzyloxycarnitinamide gives a mixture of pyrrolidinone (11% yield) and furanoyl imidate (50% yield) derivatives
From this literature《Single-step conversion of chiral carnitine and derivatives into (S)- and (R)-β-substituted γ-butyrolactones》,we know some information about this compound(58081-05-3)HPLC of Formula: 58081-05-3, but this is not all information, there are many literatures related to this compound(58081-05-3).
