BIFUNCTIONAL CHIRAL AUXILIARIES .6. ALKYLATIONS OF ENOLATES DERIVED FROM 1,3-DIACYLIMIDAZOLIDINE-2-THIONES AMD 1,3-DIACYLIMIDAZOLIDIN-2-ONES
Sodium and potassium enolates of 1,3-diacylimidazolidin-2-ones undergo clean alkylation reactions with reactive alkyl halides; the latter enolates reacting generally more stereoselectively due, it is proposed, to the lower temperature at which the reactions proceed. The reactions are all stereoregul...
