An Enzymatic Enantioselective Route to Methyl Carboxylate 2,3 - Methanohomoserine γ-Lactone; A Precursor of Chiral 2,3 - Methanohomoserine

Abstract
Enzymatic hydrolysis of Dimethyl 2 - (tetrahydropyranyl) hydroxymethyl cyclopropane 1,1 - dicarboxylate 6 with an industrial esterase, followed by a deprotection of tetrahydropyranyl ether affords the title compound in 20% yield.
