An efficient preparation of γ‐lactols and methylene‐γ‐lactols is described. Highly acid‐sensitive lactols are prepared in a concise manner by using a radicalcyclization of aluminumacetals. The precursors for the radical reactions are readily prepared from allyl or propargyl alcohols and α‐bromo acids. Functionalization of the resulting γ‐lactols and methylene‐γ‐lactols can be achieved following isolation
