Intramolecular photocyclisation of molecules containing both 3-phenylcyclopentenone and uracil rings
Abstract
Photolysis of both 3-phenyl-(5- and 6-uracilylmethyl)cyclopentenones gove single products which have been identified as 5,7-diaza-10-phenyl[7.2.1.05,9]tetracyclodecane-2,5,7-trione, respectively.
