Asymmetric alkylations of n-acyl dihydropyrimidinones
摘要:
Enantiomerically pure dihydropyrimidin-4-one 1 has been employed as a chiral auxiliary for enantioselective alkylation reactions. Acylation of 1, followed by enolate formation, alkylation and acyl cleavage, affords alpha-alkylated carboxylic acids in high chemical yield and enantiomeric purity.
