  Stereoselective lithiation and alkylation and aldol reactions of chiral 5-methyl-3-(o-aryl)-oxazolidinones

  摘要：

  Alkylation and aldol reactions carried out on axially chiral diastereoenriched oxazolidinedione derivatives were found to be highly stereoselective with respect to substitution at the 5-position of the oxazolidindione ring Thus diastereoenriched 5-methyl-3 (o-lodophenyl)-2-thioxo-4-oxazolidinone and 5-methyl-3-(o-aryl)-2 4 oxazolidinediones were prepared and lithiated at C-5 of the oxazolicline ring and the subsequent electrophilic quench with alkyl halides or benzaldehyde yielded products with the same diastereomer ratios as the starting materials (C) 2010 Elsevier Ltd All rights reserved
