## Abstract The domino reaction of 2,3‐epoxy‐1‐alcohol derivatives, namely tetrasubstituted 2,3‐epoxy‐1‐alcohols and 2‐ or 3‐alkyl trisubstituted 2,3‐epoxy‐1‐alcohols, with PhI(OCOCF~3~)~2~ in the presence of H~2~O is described in detail. In this reaction, several types of lactol derivatives can be
