Stepwise Reduction of Acetals to the Corresponding Hydrocarbons. A Mild and Effective Transformation via Carbinyl Bromides

Article abstract of DOI:10.1246/bcsj.64.2581

Stepwise reduction of two alkoxy groups in acetal was effected by the action of triethylsilane along with acetyl bromide and SnBr2 and then of tributyltinhydride (or lithium aluminium hydride) providing methyl or methylene compounds in good yields under very mild conditions.
