The Synthesis of N- Glycyl- N- [ 2-( 2-Acetamido- 2-deoxy-3-O-D-glucopyranosyl)- acetyl- l- alanyl-D- alpha- glutamyl]- L- lysyl- D-alanyl- D- Alanine as an analogue of the N, N- Disubstituted lysine glycopeptides present ...

Polycyclic compounds are known to give low carbon values by the conventional microanalytical methodl. During routine analysis over the last 15 years it has been found that perhydropolycyclic compounds, particularly those ...

A series of substituted hydrazones, arbohydrazone, thiocarbohydrazones, carbazate, etc., derived from carissone, a-cyperone and 4,5-dihydrocarissamine, and 4H,5-cyanocarissone have been synthesized. The structure of ...

A series of di-(substituted phenyl) - sulphides, disulphides, sulphoxides, sulphones, ethers, methanes, ketones and ethylenes, carrying an isothiocyanate moiety in one or both of the phenyl rings have been synthesized and ...

The structures of hayatinin and hayatin, two of the bis-benzyltetrahydroisoquinoline alkaloids isolated from the roots of Cissampelos pareira Linn. (Menispermaceae)were disscussed earlier.In the present communication, ...

Ozonolysisof tritiated salutaridinols-I and -II has afforded glycericacids whose absolute configurations have been determined bythe isotope dilution method. In this way the stereochemistry of salutaridinol-I, the precursor ...

Fruticosine and fruticosamine from Kopsia fruticosa (ker) A.DC. are isomeric heptacyclic alkaloids,C22H24N2O4, and they differ only in the configuration of the secondary alchoal residue. By combining evidence from chemical, ...
