The Uses of (2R)-Bornane-10,2-sultam
(2R)-Bornane-10,2-sultam is a reagent used to make Camphorsultam conjugates.
The Uses of (2R)-Bornane-10,2-sultam
(1S,2R)-(-)-10,2-Camphorsultam is used in the asymmetric synthesis of (S)- and (R)-N-Fmoc-S-trityl-α-methylcysteine. It is used as proton source in the synthesis of chiral α,γ-substituted γ-butyrolactones. It is also employed as a chiral probe for the optical resolution by HPLC and X-ray crystallographic determination of the absolute stereochemistry of carboxylic acids. Also used to prepare N-acryloyl derivatives which are employed as dienophiles in asymmetric Diels-Alder reactions. and for other asymmetric transformations.
The Uses of (2R)-Bornane-10,2-sultam
(1S)-(?)-2,10-Camphorsultam may be used in the asymmetric synthesis of (S)- and (R)-N-Fmoc-S-trityl-α-methylcysteine. It may be used as proton source in the synthesis of chiral α,γ-substituted γ-butyrolactones.
General Description
(1S,2R,4R)-(?)-2,10-Camphorsultam may be employed as a chiral probe for the optical resolution by HPLC and X-ray crystallographic determination of the absolute stereochemistry of carboxylic acids.
Purification Methods
The (-)-enantiomer is recrystallised from 95% EtOH and dried in a vacuum desiccator. It dissolves in dilute aqueous NaOH and can be precipitated without hydrolysis by acidifying. It forms the N-Na salt in EtOH (by addition of Na to the EtOH solution), and the salt can be methylated with MeI to give the (-)-N-Me lactam with m 80o after recrystallisation from hot H2O and has []D -59.6o (c 5, CHCl3) [Shriner et al. J Am Chem Soc 60 2794 1938]. [Oppolzer et al. Helv Chim Acta 69 1142 1986, Weismiller et al. Org Synth 69 154 1955, Beilstein 27 III/IV 1007.]
