摘要：

We prepared a series of enantiomerically pure benzyl and allyl telluronium salts 2 and 4, using the 2-exo-hydroxy-10-bornyl group as a chiral ligand, in high yield and selectivity by the reaction of chiral haloalkoxytelluranes 1 and 3 with Grignard reagents. A sharp pyramidal structure with S absolute configuration at the tellurium atom was confirmed by an X-ray analysis of 2c. (C) 1997 Published by Elsevier Science Ltd.
