Efficient parallel resolution of pentafluorophenyl active esters using quasi-enantiomeric combinations of oxazolidin-2-ones
摘要:
The parallel resolution of racemic pentafluorophenyl 2-aryl/phenylpropanoates and butanoates using an equimolar combination of quasi-enantiomeric Evans oxazolidin-2-ones is discussed. The levels of diastereoselectivity were excellent (>90% de) leading to separable quasi-enantiomeric oxazolidin-2-ones in good yield. This methodology was used to resolve a series of structurally related 2-aryl/phenylpropanoic and butanoic acids. (C) 2011 Elsevier Ltd. All rights reserved.
Parallel kinetic resolution of racemic oxazolidinones using quasi-enantiomeric active esters
摘要:
Racemic Evans' oxazolidinones were efficiently resolved using a combination of quasi-enantiomeric profens. The levels of stereocontrol were high, leading to products with predictable configurations. (c) 2007 Elsevier Ltd. All rights reserved.
