A facile enzyme assisted route to enantiomerically pure δ - lactones
摘要:
Enantiomerically pure 1,2-epoxyalkanes, obtained via enzymatic resolution of suitable precursors can serve as key building blocks for the preparation of the title compounds. Using a simple and very short synthetic protocol enantiomerically pure delta-lactones are obtained in high yields.
Enzyme assisted synthesis of enantiomerically pure δ-lactones
摘要:
Both enantiomeric series of a wide variety of optically pure 6-alkylated delta-lactones - saturated as well as unsaturated - were prepared via an enzyme mediated route. The key reaction step is the nucleophilic ring opening of enantiomerically pure alkyl-oxiranes, accessible via the corresponding beta-hydroxythioethers which can be obtained enantiomerically pure via enzyme catalyzed kinetic resolutions.
