WebAug 20, 2024 · The occurrence of a hydride transfer is dependent on the distance between the N5 atom of the reduced flavin and the atom donating or receiving the proton (Figure 2b). A distance of 3.8 Å between the two entities is optimal . It has also been shown that upon reduction, FMN adopts a butterfly-like bending of the isoalloxazine ring system . WebMar 23, 2024 · Additionally, we present our design for air-stable, reduced flavin catalysts, which is based on a conformational bias strategy and circumvents the otherwise rapid reduction of O 2 from air. Using our catalytic strategy, we were able to replace superstoichiometric amounts of the rare-earth reductant SmI 2 in a 5- exo -trig cyclization …
