  Furfuryl cations are generated via a highly efficient bismuth-catalyzed reaction of furfuryl alcohols. This systematic study provides insight on the reactivity profile of furfuryl cations towards nucleophilic substitution reactions. Novel C–C, C–N, C–O and C–S bond forming reactions of furfuryl cations have been developed, thus providing access to a diverse array of building blocks for further manipulations.

  The kinetic resolution of racemic 1-(benzothiazol-2-yl)ethanol rac-2a, 1-(benzo[b]thiophen-2-yl)ethanol rac-2b, 1 -(benzo[b]furan-3-yl)ethanol rac-2c and 1-(benzo[b]thiophen-3-yl)ethanol rac-2d was studied by enantiomer selective acylation catalyzed by a selection of commercially available and in house produced lipases. Alcoholysis of the Corresponding racemic acetates rac-3a-d catalyzed by Candida antarctica lipase B (CaLB) was also investigated. Two racemic 1-heteroarylethanols rac-2a,b were prepared by addition of the corresponding lithiated heteroarylic compounds la,b to acetaldehyde, whereas two others, rac-2c,d were synthesized by the addition of MeMgl onto the corresponding heteroaryl-carbaldehydes 1c,d. The high enantiomer selectivities of CaLB in the acylation of racemic 1-heteroarylethanols rac-2a-d allowed the determination of the enantiomeric preference of these enzymatic acetylation reactions by QM/MM [pm3/uff or hf(3-21+g**)/uff] calculations. For acetylation of each of the racemic alcohols rac-2a-d, four possible tetrahedral intermediate states were Compared and analyzed. (C) 2008 Elsevier Ltd. All rights reserved.
