(+)-Dehydroiridodiol and (-)-isodehydroiridodiol were synthesized stereoselecticely using the diastereo- and enantioselective Michael addition of chiral amide enolates to α,β-unsaturated esters.
Enzymes in organic synthesis, 26: Synthesis of enantiomerically enriched 2,3- and 3,4-dimethylpentan-5-olides by lipase-catalyzed regio- and enantioselective alcoholysis of cis- and trans-2,3-dimethylpentanedioic anhydrides

The enzyme-catalyzed regio- and enantioselective alcoholysis of racemic cis- and trans-2,3-dimethylpentanedioic anhydride in the presence of Novozym 435 from Candida antarctica afforded two of the eight possible monoesters with an enantiomeric excess higher than 90%. Regioselective reductions of these monoesters with lithium borohydride or borane/dimethyl sulfide furnished four enantiomerically highly enriched dimethylpentan-5-olides, which are versatile chiral intermediates.
