Synthesis of 2-Mono- and 2,2-Bis[2-(1H-tetrazol-5-yl)ethyl] Derivatives of Dipterocarpol

The azidation of 2,2-bis(2-cyanoethyl)-20-hydroxydammar-24-en-3-one afforded new tetrazole derivatives of natural dipterocarpol, 2-(2-cyanoethyl)-2-[2-(1H-tetrazol-5-yl)ethyl]-20-hydroxydammar-24-en- 3-ones, 2,2-bis[2-(1H-tetrazol-5-yl)ethyl]-20-hydroxydammar-24-en-3-one, and 2,2-bis[2-(1H-tetrazol-5-yl)- ethyl]-3-oxo-25,26,27-trinordammaran-(20S),24-olide. The structure of the final and intermediate products was determined by NMR spectroscopy and X-ray analysis.

DAMMARANE TRITERPENES FROM THE STEM BARK OF COMMIPHORA DALZIELLI

From the stem bark of Commiphora dalzielii the isolation and identification of the 20,24-epoxydammarane triterpenes cabraleadiol 3-acetate, cabraleadiol and cabraleone and isofouquierone are reported.Both the acetate and isofouquierone appear to be novel.The chemotaxonomic implications of findings this type of triterpene in the Burseraceae are discussed.Key Word Index - Commiphora dalzielii; Burseraceae; dammaranes; cabraleadiol; cabraleadiol 3-acetate; cabraleone; isofouquierone; chemical taxonomy.

VELLOZONE, A TETRACYCLIC TRITERPENE FROM VELLOZIA STIPITATA

The isolation of (20R)-20-hydroxy-24-methylenedammar-3-one from Vellozia stipitata is described. - Key Word Index: Vellozia stipitata; V. aloifolia; Velloziaceae; tetracyclic triterpene; (20R)-20-hydroxy-24-methylenedammar-3-one.

Synthesis and properties of 2-cyanoethoxy derivatives of dammarane triterpenoids

Cyanoethylation of dammaran-3β-ols and 3-oxime dammarene, semisynthetic derivatives of the natural dipterocarpol, afforded a series of new dammarane triterpenoids containing 2-cyanoethoxy fragment at the carbon atom in the position 3 of the tetracyclic scaffold. A notable antiviral activity was found in 20(S)-3-[(2-cyanoethoxy)imino]-dammar-24-en-20-ol and 20(S)-3-O-(2-cyanoethyl)-25,26,27-trinor-20,24-olidedammarane.

Ozonolysis of dipterocarpol and its derivatives

Oxidation of dipterocarpol and its derivatives with ozone gave compounds containing lactone, lactol, alkoxytetrahydrofuran, aldehyde, and methyl ketone fragments in the side chain, as well as 1,2,4-trioxolane fragment in the A ring. The molecular and crystalline structures of dipterocarpol were determined by X-ray analysis. Pleiades Publishing, Ltd., 2012.

Polymeric derivatives of dipterocarpol, a dammarane triterpenoid

Polymeric derivatives of dammarane triterpenoids with both labile and strong (covalent) polymer-triterpenoid bonds were prepared from N-vinylpyrrolidone copolymers. Pleiades Publishing, Inc., 2006.
