  Highly stereocontrolled sequential asymmetric Michael addition reactions with cinnamate esters - generation of three and four contiguous stereogenic centers on seven-carbon acyclic motifs

  摘要：

  The reaction of allyl and crotyl bicyclic chiral phosphonamide anions with two cinnamate esters leads to a sequential Michael reaction with excellent diastereoselectivity. The option to quench enolates with methyl iodide greatly enhances the versatility of the reaction in the synthesis of acyclic seven-carbon chains with vicinal and alternating C-methyl and C-phenyl substituents.
