(R,R)-(-)-1,2-BIS[(O-METHOXYPHENYL)(PHENYL)PHOSPHINO]ETHANE(1,5-CYCLOOCTADIENE)RHODIUM (I) TETRAFLUOROBORATE

1. Highly reactive enantioselective catalyst for the asymmetric hydrogenation of various substituted dehydroalanines to Nprotected aminoacids. Also, catalyst is very effective in the asymmetric reduction of pentapetides that contain unsaturated Phe or Tyr linkages to enkephalin, a brain peptide hormone.
2. Efficient catalyst for the asymmetric reduction of enol acetates to esters.
3. Catalyst used to prepare chiral 2-substituted succinic acid derivatives.

Orange crystalline powder

(R,R)-(-)-1,2-Ethanediylbis[(2-methoxyphenyl)phenylphosphine]rhodium(I) Tetrafluoroborate is used as a catalyst in the synthesis of Sinefungin (S487100); a natural nucleoside analog of S-adenosylmethionine that inhibits Streptococcus pneumoniae biofilm growth. Its derivatives can be used as inhibitors and structure probes for human protein lysine methyltransferase SETD2.
