Abstract
Preparations of lithium and potassium ditripylethylhydroborates are outlined. The lithium salt reduces substituted cyclohexanones with diastereoselectivities comparable with the most selective reagents known, but with the advantages that low temperatures are not required and the corresponding borane is air stable and can be quantitatively recovered. Preparations of lithium and potassium ditripylethylhydroborates are outlined. The lithium salt reduces substituted cyclohexanones with diastereoselectivities comparable with the most selective reagents known, but with the advantages that low temperatures are not required and the corresponding borane is air stable and can be quantitatively recovered. Although ditripylethylhydroborane catalyses the reduction of ketone by potassium hydride, the diastereoselectivities obtained in the catalytic process are low.
