Conjugate addition to (α,β)(α,β)-diendioate esters by lithium (α- methylbenzyl)benzylamide: Tandem addition-cyclisation versus double addition
Urones JG., Garrido NM., Díez D., Dominguez SH., Davies SG.
Strategies for obtaining either the products from tandem conjugate addition-cyclisation or from double addition in the highly stereoselective addition of lithium (R)-(β-methylbenzyl)benzylamide to (α,β)(α,β)- diendioate esters are demonstrated.
