Popis: 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.
