pseudo-enantiomeric olefinligands were designed from d-glucose and d-galactose. These ligands yield consistently excellent levels of enantioselectivity in Rh(I)-catalyzed 1,4-additions of aryl- and alkenylboronic acids to achiral enones and high diastereoselectivity with chiral substrates. Contrary to established olefinligands, they are obtained enantiomericallypure via short syntheses without racemic

carboxylesterase family, specifically catalyze intramolecular transesterification, but not hydrolysis. In this report, we synthesized analogues of Pos with various alcohol moieties, and measured the TgTCE activity together with a determination of the kinetic parameters for these analogues with a view to probe the substrate recognition mechanism of the unique non-ester-hydrolyzing TgTCEs. It was found
trans-2-Substituted-3,6-dihydro-2H-pyran-3-ols have been prepared via an aldol condensation/ring-closing metathesis/enzymatic resolution sequence. The process can be scaled up to yield gram quantities of enantiomerically pure material.
