Introduction of Oxygen Functions into the α‐Position of β‐Diketones, 7. Oxo‐Meldrum's Acids by Ozonolytic Cleavage of (Methoxymethylene)‐Meldrum's Acids (Methoxymethylene)‐Meldrum's acids 1 react with ozone in aprotic medium to form the corresponding sec. ozonides 2 („peroxyorthoformates”). Deoxygenation of 2 with PCl 3 yields Oxo‐Meldrum' acids 3 .
