摘要：
Polycyclic thiazoles, 6a and b, have been synthesised and the enantiomers resolved. Alkylation gave chiral thiazolium salts which catalyse the dimerisation of benzaldehyde to give benzoin with enantiomeric excesses up to 26%. Reasons for these results are discussed. (C) 1997 Elsevier Science Ltd.
