Synthesis of enantiopure 1-r-aryl-2-c,5-t-diphenylphospholane oxides and boranes by Pd-catalyzed C-P bond formation

New chiral enantiopure phospholane oxides 1 and boranes 5 were obtained from efficient carbon-phosphorus bond formation by organocuprate or palladium-catalyzed reactions. C-P cross-coupling reactions between chiral phosphane oxide 3 or borane 4 and variou

Synthesis and first applications of a new family of chiral monophosphine ligand: 2,5-diphenylphosphospholanes

The cyclic phosphinic acid 1-hydroxy-1-r-oxo-2c,5-t-diphenylphospholane was synthesized and resolved into enantiomers through fractional crystallization of the quinine salts. The P-phenyl, P-methyl and P-benzyl tertiary phosphine oxides were obtained from
