22(17 → 28)abeo-Lupene derivatives 5a and 6a were obtained after the acid-catalyzed E-ring expansion of 3-acetylbetulin (1a). Glycosylation of these dehydrated triterpenoids using Schmidt's trichloroacetimidate sugar donors in the presence of trime

A new semisynthetic access to germanicane-type triterpenes was achieved from betulin, a natural triterpene of the lupane family. The Wagner–Meerwein rearrangement of acetylated betulinic acid allowed the formation of the typical ring E of germanica

Germanicane-type triterpenes allobetulin ( 3 ) and 28-oxoallobetulin ( 4 ) can be obtained by the Wagner-Meerwein rearrangement of the more available lupane-type triterpenes betulin ( 1 ) and betulinic acid ( 2 ), respectively. The medical uses of be

[structure: see text] New and facile synthesis of symmetric diindolocarbazoles was developed using the copper-catalyzed Ullmann reaction. The key step is a double-intramolecular cyclization reaction realized on N-alkyl-3,6-dibromo-2,7-bis(2'aminophen
