Sj. Stanway et Ej. Thomas, 1,6-ASYMMETRIC INDUCTION IN REACTIONS BETWEEN 6-HYDROXY-5-METHYLHEX-2-ENYL(TRIBUTYL)STANNANE AND ALDEHYDES PROMOTED BY TIN(IV) BROMIDE, Tetrahedron letters, 36(19), 1995, pp. 3417-3420
(R)-6-Hydroxy-5-methylhex-2-enyl(tributyl)stannane 4 transmetallates o
n treatment with tin(IV) bromide to give an intermediate allyltin trib
romide which reacts with aldehydes to give 1-substituted (Z)-6-methylh
ept-2-ene-1,7-diols 7 with excellent anti-1,6-asymmetric induction.
