S. Ye et al., Highly diastereoselective synthesis of vinylcyclopropane derivatives with (-)-8-phenylmenthol as chiral auxiliary, J ORG CHEM, 66(17), 2001, pp. 5717-5722
The silylated telluronium. allylide 4, generated in situ from the correspon
ding telluronium salt in the presence of LiTMP, reacted with (-)-8-phenylme
nthyl alpha,beta -unsaturated esters to afford trans-2-silylvinyl-trans-3-s
ubstituted cyclopropyl esters with high diastereoselectivity in high yields
. The absolute configuration was determined by chemical transformation. A m
echanistic rationale is proposed.
