The first dynamic thermodynamic resolution of a racemic oxiranyllithium is described with selectivities of up to 82 : 18 from a selection of three types of chiral ligands (seven ligands in total). Both (-)-sparteine and its (+)-surrogate were surprisingly found to increase the enantiomerisation barrier.

Abstract
The first dynamic thermodynamic resolution of a racemic oxiranyllithium is described with selectivities of up to 82 : 18 from a selection of three types of chiral ligands (seven ligands in total). Both (-)-sparteine and its (+)-surrogate were surprisingly found to increase the enantiomerisation barrier.File in questo prodotto:
