Synthesis of peroxylactones using Mn(III)-catalyzed aerobic oxidation
The aerobic oxidation of tetronic acid in the presence of 1,1-disubstituted alkenes afforded hydroperoxyethyl-peroxylactones, while a similar reaction using 3-alkyl-substituted tetronic acids gave stable crystalline peroxylactones in good to excellent yields. The oxidation using a stoichiometric amount of manganese(III) acetate did not give the bicyclic lactone but the ethenyland/ or ethyl-tetronic acid derivatives.

Total asymmetric syntheses of (+)-blastmycinone and related γ-lactones
The freeze of the conformer was realized by the introduction of an alkyl substituent at α-position of tetronic acid using a readily available none C2 chiral auxiliary (SMP or RMP), and conducted the desired asymmetric γ- methylation. Its application to expeditious total syntheses of (+)- blastmycinone (1) and (-)-3-epi-blastmycinone (2), and to the first total synthesis of (+)-(3R,4R,5R)-4-acetoxy-5-methyl-3-tetradecyltetrahydro-2(5H)- furanone (3) was described.
