Asymmetric synthesis of SMS-Phos series' precursor and a naphthalene analogue
An efficient and high-yielding (up to 57% overall yield) asymmetric route to enantiopure P-stereogenic 1,2-bis[(o-hydroxyaryl)(phenyl)phosphino-P-borane] ethanes wherein aryl = phenyl and naphthyl, is presented. The occurring P-stereomutation is confirmed

Ferrocenyl diphosphines containing stereogenic phosphorus atoms. Synthesis and application in the rhodium-catalyzed asymmetric hydrogenation
Enantiomerically pure (R)-2-methoxyphenyl(phenyl)-O-methylphosphinite borane (1a) and CR)-1-naphthyl(phenyl)-O-methylphosphinite borane (1b) react with 1,1′-dilithioferrocene to give (S,S)-1,1′-bis(2-methoxyphenyl(phenyl)phosphino)ferrocene borane (2a) an
