Abstract
For the synthesis of metalloproteinase inhibitors the (R,R)- and (S,S)-monoethyl esters of N-Boc-pyrrolidine-3,4-dicarboxylic acid were prepared as key intermediates from the trans-diester racemate by two consecutive, highly selective enzymatic reactions. Reduction of the formed acids to the corresponding enantiopure hydroxymethyl derivatives ((R,R)- and (S,S)-ethyl N-Boc-4-hydroxymethyl-3-carboxylate) gives access to a new series of chiral building blocks.
