A. Banerji et al., REACTION OF LUPENYL ACETATE WITH M-CHLOROPERBENZOIC ACID - TRANSFORMATION OF LUPEOL TO NATURALLY-OCCURRING TRITERPENOIDS, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 34(4), 1995, pp. 338-341
Lupenyl acetate when treated with m-chloroperbenzoic acid in moist chl
oroform for 5 hr at 0-degree furnishes 3beta-acetoxy-30-norlupan-20-on
e (3), 3beta-acetoxy-30-hydroxylup-20(29)-ene (4) and 3beta-acetoxy-20
-hydroxylupan-29-al (5). Products 3 and 4 are the corresponding 3beta-
acetates of the naturally occuring 30-norlupan-3beta-ol-20-one and lup
-20(29)-ene-3beta-30-diol.
