Abstract

New 5-deazaflavins with planar chirality (dFl(n)) were synthesized in which N(3) and O(2′α) in the 10-(2′-hydroxy)phenyl group were linked by a {A figure is presented} chain (n=8,10). (+)-dFl(n=8) showed a large chiral discrimination in fluorescence quenching by (R)- and (S)-1,1′-bi-2- naphthol. (+)-dFl(n=10), which was optically stable at ambient conditions, racemized only when it was converted to the reduced form. This is the first example for redox-induced rope-skipping racemization.
