“…Porphyrins and their derivatives are a class of naturally occurring macrocyclic compounds with intense colour, that have been extensively studied [7][8][9] due to the key role played in some life processes (Figures 1 and 2) and involving their special aromatic structure (18π electrons). A suitable example that can be given is the heme group which contains an iron-porphyrin complex which coordinates oxygen and carbon dioxide for cellular carriage [10], responsible for cellular respiration, and contributing to the catalytic activities of many enzymes as cofactors [11].…”

Catalysis is a topic of continuous interest since it was discovered in chemistry centuries ago. Aiming at the advance of reactions for efficient processes, a number of approaches have been developed over the last 180 years, and more recently, porphyrins occupy an important role in this field. Porphyrins and metalloporphyrins are fascinating compounds which are involved in a number of synthetic transformations of great interest for industry and academy. The aim of this review is to cover the most recent progress in reactions catalysed by porphyrins in scalable procedures, thus presenting the state of the art in reactions of epoxidation, sulfoxidation, oxidation of alcohols to carbonyl compounds and C-H functionalization. In addition, the use of porphyrins as photocatalysts in continuous flow processes is covered.

“…Other hypervalent iodone(III) reagents 2b – g and 2i – j were synthesized from the corresponding commercial iodoarenes by oxidations, according to the literature procedures [52,53,54,55]. The N -protected uracils 1b , 1c , and 1f were prepared from uracil by the known methods [56,57,58]. Solvents and all other starting materials were obtained from commercial suppliers and used without further purification.…”

Synthesis of Uracil-Iodonium(III) Salts for Practical Utilization as Nucleobase Synthetic Modules

et al. 2019

Iodonium(III) salts bearing uracil moieties have recently appeared in the literature, but their structural scope and utilization are limited because of their hygroscopic characteristics. In this study, we describe our detailed investigations for synthesizing a series of uracil iodonium(III) salts derived with various structural motifs and counterions. These new compounds have been utilized as attractive synthetic modules in constructing functionalized nucleobase and nucleosides.
