Efficient, large-scale preparation of (R)- and (S)-1-(2,4,6-triisopropylphenyl)ethanol, versatile chiral auxiliary for cyclopentenone, gamma-butyrolactone, and gamma-butyrolactam synthesis
A particularly efficacious, low-cost preparation of both (R)- and (S)-triisopropylphenyl)ethanol, useful chiral controllers in the dichloroketene-enol ether cycloaddition reaction, has been developed. Copyright (C) 1996 Elsevier Science Ltd
