2‐Quinolone 2 , quinoline 3 , coumarin (2 H ‐1‐benzopyran‐ 2 ‐one) 5 , and 2 H ‐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.
