  The allylic telluronium ylides 2a-2c, generated in situ from the corresponding telluronium salts 1a-1c in the presence of a lithium salt, reacted with alpha,beta-unsaturated esters or amides to afford trans-2-vinyl-trans-3-substituted cyclopropyl esters or amides, respectively, with high selectivity and generally excellent yields. in the absence of lithium salts, the stereoselectivity of these reactions changed to give cis-2-vinyl-trans-3-substituted cyclopropyl esters or amides. The ratio of the two isomers 4 and 5 can be tuned from 99:1 to 1:99. Other factors, such as temperature, solvents, and amounts of base, are also shown to influence the stereochemistry of this reaction. mechanism for tuning of the reaction stereochemistry by simply varying reaction conditions is proposed.
