Popis: The enzyme-catalyzed kinetic resolution of (±)-(3aα,4α,6aα)-4-acetoxy-1,3-dibenzyl-3a,4,6,6a-tetrahydro-1H-thieno[3,4-d]imidazol-2(3H)-one [(RS)-(3a)] was examined. Lipase B from Pseudomonas fragi and rabbit liver esterase gave (−)-[3aR-(3aα,4α,6aα)]-1,3-dibenzyl-3a,4,6,6a-tetrahydro-4-hydroxy-1H-thieno[3,4-d]imidazol-2(3H)-one [(R)-(2)], while Streptomyces rochei var. volubilis gave the alcohol (S)-(2), which is a key intermediate in the synthesis of d-biotin, with high enantioselectivity.
