摘要

Abstract 2-Quinolone 2, quinoline 3, coumarin (2H-1-benzopyran-2-one) 5, and 2H-1- benzopyran hemiacetal 6 were synthesized by photocyclization reaction of traans-o- aminocinnamoyl derivatives trans-1 and trans-o-hydroxycinnamoyl derivatives trans-4. The reaction proceeds through trans-cis isomerization followed by intramolecular cyclization.
