Abstract

A three-step synthesis of optically pure (R)-(-)-1, 1, 2-triphenyl-3, 3-dimethylbutane from (R)-(- )-a-tert-butylphenylacetic acid has been accomplished. The synthesis of a-phenylneopentyl chloroformate from optically pure (R)-(+)-l-phenyl-2, 2-dimethyl-l-propanol was followed by decomposition at 95" C to give samples of
