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.

Application

(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.

A highly useful method for the synthesis of optically active alpha,gamma-substituted gamma-butyrolactones has been developed. The SmI(2)-induced reductive coupling of chiral 2-alkyl acrylates derived from isosorbide with ketones in the presence of (1S)-(-)-2,10-camphorsultam as a proton source give the chiral

(1R)-(+)-2,10- and (1S)-(-)-2,10-camphorsultam were acylated with ethyl 2-phenylthiazoline 4-carboxylate to afford (+)- and (-)-2-phenylthiazolinylcamphorsultam, which were stereoselectively alkylated with MeI in the presence of n-BuLi. Alkylation of these phenylthiazolinylcamphorsultams occurred from the beta-face rather than alpha-face, resulting in the formation
