Hydrogenolyses of 3-hydroxycholest-4-enes by mixed hydrides
Abstract
Hydrogenolysis of 3α-hydroxycholest-4-ene by aluminium chloride and lithium aluminium deuteride probably proceeds through the formation of an allyl carbonium ion. In the case of 3β-hydroxycholest-4-ene, the results seem to indicate that the reaction does not proceed only through an SN1 mechanism.
