Both individual steps, i.e. the allylic alcohol isomerization and the TH of the carbonyl intermediate, require the use of a base as co-catalyst to promote the formation of the active metal-hydride species. As expected, very low conversions (0–15%) of the substrate were observed in the absence of base
