摘要
Allylation of amino-acid esters gives rise to intermediate quaternary ammonium salts, which undergo proton abstraction to give ylides and [2,3]-sigmatropic rearrangement. The resulting alpha-amino-acid derivatives can be subjected to N-deallylation to provide a rapid access to alpha-allyl-alpha-amino-esters. Using N-benzyl proline methyl ester, chirality transfer from carbon to nitrogen then back to carbon takes place.
