Sg. Allenmark et Ac. Andersson, LIPASE-CATALYZED KINETIC RESOLUTION OF A SERIES OF ESTERS HAVING A SULFOXIDE GROUP AS THE STEREOGENIC CENTER, Tetrahedron : asymmetry, 4(11), 1993, pp. 2371-2376
A series of methyl 2-(alkylsulfinyl)benzoates (alkyl = C1, n-C4, n-C-8
, n-C-12 and n-C-16) was investigated with respect to substrate behavi
our and enantioselectivity in a lipase (Candida rugosa)-catalyzed hydr
olytic reaction. Although three bonds separate the stereogenic centre
and the ester carbonyl group, very high enantioselectivity values (>10
0) could be obtained. It was found that the enzyme consistently showed
a strong kinetic preference for the (-)-(S)-enantiomer.
