24-METHYLENE-25-METHYLCYCLOARTANOL AND 24α-ETHYL-5α-CHOLESTAN-3α-OL FROM NEOLITSA SERICEA

A new triterpene alcohol isolated from the stems of Neolitsea sericea was shown to have the structure 24-methylene-25-methylcycloartanol.Moreover, in addition to the common triterpene alcohols and sterols, the following uncommon compounds were isolated from the plant material and were identified: (24E)- and (24Z)-24-ethylidenecycloartanol, (24E)- and (24Z)-24-ethylidene-5α-lanost-8-en-3β-ol, 24 methylene-24(25)-dihydroparkeol, 24-methylene-5α-lanosta-7,9(11)-dien-3β-ol, 24-methylenedammarenol, both C-24 epimers of 14α,24-dimethyl-5α-cholest-9(11)-en-3β-ol, 14α-methyl-24α-ethyl-5α-cholest-9(11)-en-3β-ol, and 24α-ethyl-5α-cholestan-3α-ol. Key words: Neolitsea sericea; Lauraceae; triterpene alcohol; sterol; 24-methylene-25-methylcycloartanol; 24α-ethyl-5α-cholestan-3α-ol.

TETRACYCLIC TRITERPENES. X. SOLVENT EFFECT IN REACTIONS OF TETRASUBSTITUTED TRITERPENOIDAL OLEFINS WITH OZONE. AN ALLYLIC OXIDATION

The highly hindered 8,9 double bond in lanostane derivatives was found susceptible to oxidation with ozone.The reaction depends on the polarity of the solvent.It is proposed that the structure of the initial complex formed between the olefin and ozone is influenced by the reaction medium.Reaction of 3β-acetoxy-5α-lanost-8-ene with ozone gives 8α,9α-epoxide in methylene chloride, while 3β-acetoxy-5-α-lanost-8-en-7-one, an allylic oxidation product, is the main compound formed in ethyl acetate.

Lanostane-to-cucurbitane transformation

Westphalen-type rearrangement of a 9α-hydroxy-11-ketone derived from lanosterol resulted in formation of two 19(10->9β)abeo-lanostenes representing the first lanostane-to-cucurbitane transformation.A novel ring A aromatic 9,10-seco derivative was formed a
