Zurückführung der Konfiguration des (natürlichen) Sphingosins auf die der Derythro‐2‐Amino‐3,4‐dioxy‐buttersäure. 12. Mitteilung über Sphingosin und Sphingolipoide

Abstract: Volumen XXXVII, Fasciculus v (1954) -No. 172-173. SUMMARY.Using methylglyoxal as the u-dicarbonyl component in the new pyridazine synthesis described in an earlier publication, two isomeric methyl-5-cyano-pyridazones-( 6 ) are obtained with cyslnoacetic acid hydrazide. The position of the methyl groups has been proved.Starting from 3,4-dimethyl-5-cyano-pyridazone-6 the hitherto undescribed 3,4-dimethyl-pyridazine has been prepared.Forschungslaboratorien der CIBA AktiengeseZZschaft, Basel. 1471Pharmazeutische A… Show more

“…Carbon atom 2 has D-configuration (CARTER et al 1951;KIss et al 1954;KLENK et al 1955) and the double bond trans-configuration (MISLOW 1952, MARINETTI et al 1954. One of the most suitable derivatives of sphingosine is the crystalline triacetylsphingosine.…”

“…The absolute configuration of sphingosine was initially assigned as D-erythro via chemical relay reactions in the 1950s. 4 In the 1990s, Nakanishi and Berova et al developed stereochemical analysis methods for sphingolipids utilizing HPLC 5 and circular dichroism (CD) 6 techniques. Although these methods are excellent both in sensitivity and reliability, they still have several drawbacks.…”

“…However, the stereochemistry of most sphingolipids remains unassigned due to a lack of facile method for determining the relative and absolute configurations of such an amphiphilic long-chain base. The absolute configuration of sphingosine was initially assigned as d - erythro via chemical relay reactions in the 1950s . In the 1990s, Nakanishi and Berova et al developed stereochemical analysis methods for sphingolipids utilizing HPLC and circular dichroism (CD) techniques.…”
