Introduction of Oxygen Functions into the α-Position of β-Diketons. 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 PCl3 yields Oxo-Meldrum's acids 3.

Introduction of Oxygen Functions into the α-Position of β-Diketones, 8. Ozonolysis of Sulfonium Ylides

(Dimethylsulfonio)diacylmethanides 1, prepared by known methods, are cleaved by equimolar amounts of ozone in aprotic medium yielding vicinal triketones 2 and DMSO.Peroxydic reaction products are not detectable.
