Abstract

Abstract Oxetane is a potential intermediate that is enzymatically formed during the repair of (6–4) DNA lesions by special repair enzymes (6–4 DNA photolyases). These enzymes use a reduced and deprotonated flavin to cleave the oxetane by single electron donation. Herein we report synthesis of DNA hairpin model compounds containing a flavin as the hairpin head and two different oxetanes in the stem structure of the hairpin. The data show that ...
