—— | 3-acetoxy-cholesta-3,5-diene | 2309-32-2 | C29H46O2 | 426.683 |
The photolysis of 3-alkoxycholesta-3,5-dienes in an alcohol has been found to result in a stereospecific addition of the alcohol to the Δ3 double bond with formation of β,γ-unsaturated ketals. On silica gel, the non-cyclic β,γ-unsaturated ketals gave cholest-5-en-3-one.
