(1S, 9S)-(-)-1,9-BIS[(TERT-BUTYLDIMETHYLSILYLOXY)METHYL]-5-CYANOSEMICORRIN Usage And Synthesis
Application
(1S, 9S)-(-)-1,9-BIS[(TERT-BUTYLDIMETHYLSILYLOXY)METHYL]-5-CYANOSEMICORRIN is a chiral ligand that can be used for enantiocontrolled metal-catalyzed reactions, such as the cobalt-catalyzed conjugate reduction of α,β-unsaturated carboxylic acid esters and amides or the copper-catalyzed cyclopropanation of olefins.
storage
As crystalline solids, semicorrins of this type are stable at ambient temperature; for longer periods, storage at -20 °C is recommended.
