Bandaranayake, Wickramasinghe M.
, p. 255 - 258 (1980)
The following terpenoids were identified in the oleoresin, bark and timber of Canarium zeylanicum: 3β-hydroxyurs-12-en-11-one, 3β-hydroxyolean-12-en-11-one, olean-12-en-3,11-dione, urs-12-en-3,11-dione, α- and β-amyrin, α- and β-amyrenone, taraxerol, sitosterol, canaric acid, elemene, elemol, α-pinene, α- and β-phellandrene, limonene, terpineol, and cavrone. - Key Word Index - Canarium zeylanicum; Burseraceae; oleoresin; bark; timber; monoterpenoids; sesquiterpenoids; triterpenoids; 3β-hydroxyurs-12-en-11-one (neoilexonol); 3β-hydroxyolean-12-en-11-one; olean-12-en-3,11-dione; urs-12-en-3,11-dione; elemene; elemol; α-amyrine and β-amyrine; α- and β-amyrenone; canaric acid; taraxerol; sitosterol.
Biomimetic oxidation of 3β-hydroxy-olean-12-ene and its acetoxy derivative with monooxygen donors catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides in dichloromethane

The oxidation of 3β-hydroxy-olean-12-ene with monooxygen donors catalyzed by 5,10,15,20-tetraarylporphyrinatoiron(III) chlorides in dichloromethane gives 3β,11α-dihydroxy-olean-12-ene, 3-oxo-olean-12-ene, 3,11-dioxo-olean-12-ene and 3β-hydroxy-olean-9(11),12-diene whereas the oxidation of 3β-acetoxy-olean-12-ene under similar conditions gives 11(-hydroxy-3β-acetoxy-olean-12-ene, 11-oxo-3β-acetoxy-olean-12-ene and 3β-acetoxy-olean-9(11),12-diene in moderate yields.
Functionalisation of Saturated Hydrocarbons. Part 6. Selective Oxidation of Steroids and Related Compounds
Barton, Derek H. R.,Boivin, Jean,Hill, Christopher H.
, p. 1797 - 1804 (2007/10/02)
The oxidation of a series of steroids by the Gif system gives, almost without exception, the 20-ketone as major isolated product.The side-chain cleavage is made more selective by modification of rings A or B.The oxidation of oleana-1,12-diene-3,11-dione has also been studied and the two principal products have been identified.
