Single enantiomer free-radical chemistry—Lewis acid-mediated reductions of racemic halides using chiral non-racemic stannanes

New distannanes containing the chiral 2-(4-isopropyl-2-oxazolinyl)-5-phenyl ligand

“…There have been several reports concerning potentially intramolecularly coordinated tin hydrides in which the tin atom is coordinated to nitrogen from the ligand [1][2][3][4][5][6][7][8]. However, to the best of our knowledge the corresponding distannanes have not been reported yet.…”

Structural assignment of organotin hydrides containing the oxazoline ligand

“…The organotin hydrides with the potentially chelating ligands have been receiving increasing attention in recent years due to their ability for enantioselective quenching of trigonal sp 2 intermediates such as radicals [1][2][3][4][5][6][7][8].We have recently described the synthesis and NMR study of organotin hydrides 1-5 containing the chiral oxazoline moiety ( Fig. 1) [9,10].…”

New chiral tin compounds containing the 2-(4-isopropyl-2-oxazolinyl)-5-phenyl ligand

“…There have been several reports concerning potentially intramolecularly coordinated tin compounds, including hydrides in which the tin atom is coordinated to nitrogen [1][2][3][4][5][6][7][8] or phosphorus [9] from the ligand. We have recently described the synthesis and NMR study of tin hydrides 1-3 containing the chiral oxazoline moiety (Fig.…”
