摘要:
The syntheses of three new optically active β-mercaptoalcohols, ( R)-1, 1-diphenyl-2-mercapto-3-methyl-1-butanol, ( R)1,1-diphenyl-2-mercapto-4-methyl-1-pentanol, and ( R)-1, 1-diphenyl-2-mercapto-1-benzenepropanol from the corresponding amino acids are described. The enantiomeric excesses of thee β-mercaptoalcohols were determined by 1H NMR as their ( S)-mandeloyl derivatives.
