A General Convenient One-Pot Procedure for the Conversion of Carboxylic Acids into theirt-Butyl Esters which is also Applicable to Aliphatic Carboxylic Acids
Homoallylic amines as efficient chiral inducing frameworks in the conjugate addition of amides to α,β-unsaturated esters. An entry to enantio-enriched diversely substituted amines
The diastereoselective conjugateaddition of secondary homoallylamines, obtained in the enantioenriched form via allylmetallation of imines, to α,β-unsaturated esters is reported. This method allows access to valuable building blocks as well as heterocyclic skeletons, providing tertiary amines bearing two chains integrating a stereogenic center adjacent to the nitrogen atom.
