Abstract
The photodimer of coumarin is shown to have the head-to-head cis cyclobutane structure I. An isomer, obtained by the lactonization of o-hydroxy-trans-cinnamic acid, is shown to have the head-to-tail trans structure II. The photodimers of o-methoxy- and o-hydroxy-trans-cinnamic acids have been interrelated.
