Stereospecific synthesis of amphetamines
Regioselective addition of aryl lithium to commercially available (S)-(+)-propylene oxide provides the corresponding (S)-aryl-2-propanol. The (R)-amphetamine is obtained by conversion of the alcohol to the tosylate followed by azide displacement and hydrogenation. Mitsunobu conversion of the alcohol to the (R)-bromide followed by azide displacement and hydrogenation affords the (S)-amphetamine....
متن کاملTotal synthesis of stereospecific sphingosine and ceramide.
A small-scale synthesis of the four sphingosine stereoisomers (d-erythro, l-erythro, d-threo, and l-threo) and lignoceroyl d- and l-erythro-sphingosines, which is suitable for synthesis of tritium-labeled compounds, is described. Ethyl dl-erythro-2-acetamino-3-hydroxy-4t-octadecenoate was esterified with l(+)-acetylmandeloyl chloride and the two diastereomers obtained were separated from each o...
متن کاملStereospecific synthesis of a twinned alanine ester.
Reaction between 1,2-bis(2-hydroxyphenyl)-ethylenediamine (hpen) and methyl pyruvate gives the diaza-Cope rearrangement product with good yield and excellent stereospecificity. The product containing two chiral quaternary carbon centers is characterized by high performance liquid chromatography and X-ray crystallography. DFT computation provides insight into why the diaza-Cope rearrangement tak...
متن کاملCyclodextrins in Asymmetric and Stereospecific Synthesis
Since their discovery, cyclodextrins have widely been used as green and easily available alternatives to promoters or catalysts of different chemical reactions in water. This review covers the research and application of cyclodextrins and their derivatives in asymmetric and stereospecific syntheses, with their division into three main groups: (1) cyclodextrins promoting asymmetric and stereospe...
متن کاملIn vitro anti-viral effect of β-santalol against influenza viral replication.
The anti-influenza A/HK (H3N2) virus activity of β-santalol was evaluated in MDCK cells and investigated the effect of β-santalol on synthesis of viral mRNAs. β-Santalol was investigated for its antiviral activity against influenza A/HK (H3N2) virus using a cytopathic effect (CPE) reduction method. β-Santalol exhibited anti-influenza A/HK (H3N2) virus activity of 86% with no cytotoxicity at the...
