Application

Atropisomeric MeOBIPHEP ligands
(R)-(6,6′-Dimethoxybiphenyl-2,2′-diyl)bis[bis(3,5-dimethylphenyl)phosphine] can be used as a ligand:
  • In the synthesis of (S)-3-amino-4-methoxy-butan-1-ol, a key starting material for many pharmaceutical drugs.
  • In the synthesis of 3-substituted indanones through the reductive Heck reaction of chalcones with various amines.
  • In the palladium-catalyzed Tsuji-Trost cyclizations of aldehydes to yield vinylcyclopentane derivatives.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
