Enantioselective synthesis of 2-substituted 4-aminobutanoic acid (GABA) analogues via cyanomethylation of chiral enolates
Cyanomethylation by bromoacetonitrile of sodium or lithium enolates derived from (4S,5R)-3-acyl-4-methyl-5-phenyl-1,3-oxazolidin-2-ones usually shows good stereoselecrivity; although the reaction of 3-(3-carboxypropanoyl)oxazolidinone 5d is exceptionally
