The metal-catalyzed stereoselective 1,3-dipolar cycloaddition of azomethine ylides and acrylates using recyclable meso-hydrobenzoin-derived chiral auxiliaries is described. Cleavage of the auxiliary leads to highly substituted pyrrolidines in up to 87% en

Three m-hydrobenzoin derived chiral hydrobenzoin mono-tert-butyl ethers were synthesized by a new reaction pathway and tested as chiral auxiliaries in the L-selectride mediated stereoselective reduction of their corresponding phenyl glyoxylates. As a result, improved stereoselectivities of up to a ratio of 92:8 compared to 84:16 with the initially examined analogous benzyl ether were achieved.
Chiral linker. Part 2: Synthesis and evaluation of a novel, reusable solid-supported open chain chiral auxiliary derived from m-hydrobenzoin for the diastereoselective reduction of α-keto esters

Three novel m-hydrobenzoin derived chiral hydrobenzoin mono-alkyl ethers were synthesized and evaluated as open chain chiral auxiliaries in the L-selectrideR/ZnCl2 mediated stereoselective reduction of their corresponding phenyl glyoxylates, resulting in des of up to 91%. The optimized auxiliary structure was immobilized on commercially available Wang-resin by using the ether substituent as a sublinking unit and applied as a reusable solid-supported chiral auxiliary in the same type of reaction with only little loss of stereofacial selectivity.
