(-)-Sparteine-mediated stereoselective intramolecular conjugate addition reactions of dienes and enynes
Oestreich,Hoppe
, p. 1881 - 1884 (1999)
Enantioenriched carbanionic pairs generated by the asymmetric deprotonation of carbamate esters with the chiral base s-butyllithium/(-)- sparteine undergo smoothly intramolecular conjugate addition reactions to dienes and enynes in high yields.
