Preparation of homochiral 9-anthryl-tert-butylcarbinol. The configurational and conformational NMR study of its carbamate derivatives
摘要:
The homochiral carbamates of 9-anthryl-tert-butylcarbinol were prepared and their conformational equilibrium was studied. The absolute configuration was determined by comparison of the NMR data with MM calculations. The enantiomers of the alcohol were obtained after chromatographic separation of carbamate derivatives and their hydrolysis. The same homochiral alcohols were prepared by direct chiral column chromatography.

GRAPHICSThe chiral monocinchona derivative shown, synthesized in one step from two efficiently prepared chiral building blocks, was designed under mechanistic guidance as a catalyst for the enantio- and position-selective dihydroxylation of the terminal isopropylidene group of polylsoprenoids. Its efficacy as a synthetic reagent for this purpose was demonstrated for several different substrates.
