Abstract

Abstract The conjugate allylation of a homologous series of α, β-unsaturated cyclic esters 8- 10 by addition of diallylcuprate (method A), fluoride ion catalyzed addition of trimethylallylsilane (method B), and aluminium tris (2, 6-diphenylphenoxide)(ATPH)- mediated addition of allyllithium (method C) was investigated. Method A was not selective in all cases. For methods B and C an influence of ester moiety and ring size on the ...
