Abstract

Ozonolyses of four symmetrically substituted (13a–13d) and of four unsymmetrically substituted acetylenes (17a–17d) gave all of the expected α‐oxo methoxyhydroperoxides (14a–14d, 18ae–18de, 19ae–19de) with good selectivities. The labile, non‐isolable hydroperoxides were converted into the corresponding O‐methyl oximes (15, 18f, 19f), which could be isolated as stable compounds.
