The structural study of internal [2+2] photodimers of the derivatives of 1,1'-trimethylene-bis-(5-fluoro) uracil.
The structure of internal [2+2] photodimers of 1,1'-trimethylene-bis-(5-fluoro) uracil derivatives has been studied. All investigated compounds have cis-syn geometry with puckered endocyclic cyclobutane ring and chair-like conformation of 1,3-diazacycloheptane ring.
