Stereospecific DearomatisingCyclisation of Tertiary α-Amidoorganolithiums

Abstract

Lithiation of benzamides derived from a chiral and enantiomerically pure .alpha.-methylbenzylamine leads to diastereoselective and regioselective dearomatising cyclisations with overall conservation of the stereochem. of the starting stereogenic center. [on SciFinder (R)]
