Bv. Nguyen et al., STRUCTURE VERSUS ENANTIOSELECTIVITY IN PSEUDOMONAS-CEPACIA LIPASE-CATALYZED TRANSESTERIFICATIONS - ENANTIOSELECTIVE ACYLATIONS OF PRIMARY 2-METHYLALCOHOLS, Tetrahedron : asymmetry, 8(7), 1997, pp. 983-986
The enantioselectivities of lipase from Pseudomonas cepacia (Amano PS)
towards a series of primary 2-methyl-omega-(2-thienyl)alkanols using
vinyl acetate as the acyl donor in transesterifications in organic sol
vents have been studied. It was found to be important to place the thi
ophene ring in the correct position in the chain. In terms of enantios
electivity, we found that the number of methylene groups between the s
tereogenic centre and the aromatic ring in chiral omega-aryl-2-methyla
lkanols ought to be one. (C) 1997 Elsevier Science Ltd.
