✦ Synopsis

Baeyer-Villiger reaction / Lactones / Methyltrioxorhenium / Catalysis / Oxidations / Cyclobutanones / Ketones γ-Butyrolactones were obtained in good yields and high rings, and chlorine substituents. A trimethylsiloxysubstituted ketone was converted directly into a hydro-regioselectivity by a Baeyer-Villiger oxidation with H 2 O 2 catalysed by methyltrioxorhenium. The lactonization was xylated lactone in good yield and regioselectively. chemoselective in the presence of double bonds, aromatic with chiral diphosphanes. Since 1994 there have been a few
