摘要
Asymmetric induction in the photochemistry of a linearly conjugated benzocyclohexadienone derivative has been achieved for the first time through the use of the solid state ionic chiral auxiliary method. Enantiomeric excesses as high as 70-80% at reasonable conversions are readily attainable. Crystal structures for both reactant and product are reported. (C) 1999 Elsevier Science Ltd.
