TRITERPENOIDS FROM ABIES SPECIES - 22 - ISOLATION OF THE CYCLIC TAUTOMER OF (24Z)-3,23-DIOXOLANOSTA-8,24-DIEN-26-OIC ACID, A NEW COMPONENT OF THE ACIDIC FRACTION OF THE EXTRACT FROM SIBERIAN FIR NEEDLE
Vv. Grishko et al., TRITERPENOIDS FROM ABIES SPECIES - 22 - ISOLATION OF THE CYCLIC TAUTOMER OF (24Z)-3,23-DIOXOLANOSTA-8,24-DIEN-26-OIC ACID, A NEW COMPONENT OF THE ACIDIC FRACTION OF THE EXTRACT FROM SIBERIAN FIR NEEDLE, Russian chemical bulletin, 47(3), 1998, pp. 502-504
A new component, namely, the cyclic tautomer of previously unknown (24
Z)3,23-dioxolanosta-8 ,24-dien-26-oic acid, was isolated from the acid
ic fraction of the extract from Siberian fir needle. The structure of
the title compound was established based on the H-1 NMR and circular d
ichroism spectra.
