T. Yamano et al., SYNTHESIS OF D-BIOTIN CHIRAL INTERMEDIATES VIA A BIOCHEMICAL METHOD, Bulletin of the Chemical Society of Japan, 66(5), 1993, pp. 1456-1460
The enzyme-catalyzed kinetic resolution of 6,6a-tetrahydro-1H-thieno[3
,4-d]imidazol-2(3H)-one [(RS)-(3a)] was examined. Lipase B from Pseudo
monas fragi and rabbit liver esterase gave ahydro-4-hydroxy-1H-thieno[
3,4-Aimidazol-2(3H)-one [(R)-(2)], while Streptomyces rochei var. volu
bilis gave the alcohol (S)-(2), which is a key intermediate in the syn
thesis of d-biotin, with high enantioselectivity.
