Excited State Reactions of Oxazoles and Their Derivatives. Part II: Photoinduced Inter- and Intramolecular Cycloadditions

I. Šagud and M. Šindler-Kulyk

Abstract

The oxazole ring in a complex system has a substantial impact on the reactions in ground and excited state. By cyclisation, cycloaddition and isomerization reactions in the excited state new complex polycyclic structures are formed that are interesting for further investigation. Of particular interest are 2,5-, 2,4-disubstituted and 2,4,5-trisubstituted oxazole structures in which one of the substituents is a conjugated vinyl-styryl segment. In this paper a detailed literature review is given into photoinduced inter- and intramolecular reactions of oxazole derivatives.
