摘要：

The synthesis of enantiomerically pure palladium cyclic allyl complexes is accomplished by reaction of "PdHBr" with several chiral cyclic terpenes. The strategy used involves a 100% stereoselective Pd-migration from an attached chain to the ring through a chiral carbon ("gated migration"). "PdHBr" species are produced by beta-H elimination in the benzylic moiety of [Pd-2(mu-Br)(2)(eta(3)-PfCH(2)CHPh)(2)] (1, Pf = C6F5). The allylic complexes prepared are transformed by carbonylation reactions into chiral unsaturated methyl esters.
