  Diastereoselective Synthesis and Stereochemical Research of Optically Pure Telluronium Salts

  摘要：

  The synthesis of optically pure telluronium salts 4a-i, using the 2-exo-hydroxy-10-bornyl group as a chiral ligand, has been achieved in high yield and selectivity by the reaction of chiral alkoxytelluranes 3a-i with organolithium and Grignard reagents. Both diastereoisomers of ethyl(2-exo-hydroxy-10-bornyl)methyltelluronium chloride (4a,b) and butyl(2-exo-hydroxy-10-bornyl)methyltelluronium chloride (4c,d) have been synthesized in optically pure form in high yield and with excellent diastereoselectivity. The method has been used for the asymmetric synthesis of chiral benzyl- and allyltelluronium salts 5a-h. Structures of these salts have been confirmed by X-ray analyses of 4a and 4b, which indicated that all of the salts have their pyramidal geometrical structures around the tellurium atom. The thermal and optical stability and the possible mechanisms of the reaction are also discussed.

  The first synthesis and isolation of optically pure Te-chiral-alkoxytelluranes 1 and 8 have been developed using the 2-exo-hydroxy-10-bornyl group as a chiral ligand. A distorted trigonal bipyramidal (TBP) structure of ii with R configuration was confirmed by the X-ray analysis. Copyright (C) 1996 Published by Elsevier Science Ltd

  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.
