BIFUNCTIONAL CHIRAL AUXILIARIES-8 - UTILIZATION OF TARTARIC ACID-DERIVED AUXILIARIES IN ALDOL AND ALKYLATION REACTIONS
The boron enolates of three new homochiral C2 symmetric 1,3-diacylimidazolidin-2-ones prepared from natural tartaric acid undergo highly diastereoselective aldol and alkylation reactions. Cleavage of these diastereomerically pure, adducts gives homochiral (1R,2S)-1-phenyl-2-methylpropane-1,3-diol an...
