F. Giordano et al., REACTION OF STEROLS CONTAINING THE 7,14-DIENE OR 8,14-DIENE SYSTEM WITH RUTHENIUM TETRAOXIDE - FORMATION OF EPOXYSTEROLS, Journal of chemical research. Synopses, (2), 1995, pp. 52-53
The reaction of ruthenium tetraoxide with the 7,14- and 8,14-diene ste
rols 7 and 2, respectively, performed using equimolar amounts of the o
xidant in acetone-water at low temperature, gives mainly epoxides.
