A Very Efficient Alkene Epoxidation by Magnesium Monoperoxyphthalate Catalysed by Manganese Porphyrins
Querci, Cecilia,Ricci, Marco
, p. 889 - 890 (1989)
Mn-porphyrins catalyse the epoxidation of various alkenes by magnesium monoperoxyphthalate: with 0.125-1 percent of tetra-2,6-dichlorophenylporphirinatomanganese(III) acetate as a catalyst, alkene conversion is nearly complete within 0.5-5 minutes at 0 de

Enzymatic Hydrolysis of Alkyl 3,4-Epoxybutyrates. A New Route to (R)-(-)-Carnitine Chloride
Bianchi, Daniele,Cabri, Walter,Cesti, Pietro,Francalanci, Franco,Ricci, Marco
, p. 104 - 107 (2007/10/02)
The enzyme-catalyzed hydrolysis of alkyl 3,4-epoxybutyrates to the corresponding epoxy acids is reported.By using esterases the reaction occurred with good stereoselectivity leading to optically active unreacted esters of R configuration.With proteases the stereoselectivity was reversed, and the S enantiomer of the unreacted ester was recovered, albeit in lover enantiomeric excess.Finally, upon preliminary optimization of the reaction conditions, a new synthesis of (R)-(-)-carnitine chloride by the successive use of a stereoselective and of a nonstereoselective enzymatic hydrolysis is shown.
