Abstract
There is an ever-increasing demand for impurity compounds for use in impurity profiling as regulatory agencies seek information during registration. Herein, we report the FeCl3-catalyzed oxidative decarboxylation of aryl- and heteroaryl acetic acids to the corresponding carbonyl compounds. A variety of useful aldehydes and ketones were prepared in a simple one-pot transformation by employing an environmentally benign, low-cost, and readily available iron salt. The utility of this method has been demonstrated by preparing five valuable API impurities including a multi-gram-scale synthesis of ketorolac impurity B for the first time.

Ciprofloxacin degradation by first-, second-, and third-generation manganese porphyrins. JOURNAL OF HAZARDOUS MATERIALS 2018; 360:445-451.

Abstract
A range of hydrophobic first-, second-, and third-generation manganese porphyrins (MnPs) was investigated as cytochrome P450 models for degradation of the antibiotic ciprofloxacin (CIP). The experiments were carried out under mild conditions; oxidants such as iodosylbenzene (PhIO), H2O2, and meta-chloroperbenzoic acid were employed. The PhIO system yielded the best results: CIP degradation ranged between 56% and 76%. CIP degradation was not directly related to MnP generation. The second-generation MnP afforded the best result with the advantage that it required less preparation effort as compared to the third-generation MnP. Some new degradation products in MnP-mediated ciprofloxacin degradation were proposed, and the products of the reaction are not cytotoxic under the conditions evaluated.

Molecules 2016; 21:E964. [PMID: 27455229 PMCID: PMC6272862 DOI: 10.3390/molecules21070964] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2016] [Revised: 07/17/2016] [Accepted: 07/19/2016] [Indexed: 02/03/2023] Open
Abstract
Synthetic and bioinspired metalloporphyrins are a class of redox-active catalysts able to emulate several enzymes such as cytochromes P450, ligninolytic peroxidases, and peroxygenases. Their ability to perform oxidation and degradation of recalcitrant compounds, including aliphatic hydrocarbons, phenolic and non-phenolic aromatic compounds, sulfides, and nitroso-compounds, has been deeply investigated. Such a broad substrate specificity has suggested their use also in the bleaching of textile plant wastewaters. In fact, industrial dyes belong to very different chemical classes, being their effective and inexpensive oxidation an important challenge from both economic and environmental perspective. Accordingly, we review here the most widespread synthetic metalloporphyrins, and the most promising formulations for large-scale applications. In particular, we focus on the most convenient approaches for immobilization to conceive economical affordable processes. Then, the molecular routes of catalysis and the reported substrate specificity on the treatment of the most diffused textile dyes are encompassed, including the use of redox mediators and the comparison with the most common biological and enzymatic alternative, in order to depict an updated picture of a very promising field for large-scale applications.

Abstract
Metalloporphyrins (MPs) are known to catalyze in vitro a broad range of
cytochrome P450-mediated reactions occurring in vivo. Most of the
biomimetic research using MPs in oxidative catalysis has been directed towards
the oxidation of organic compounds presenting significant reactivity features in
one functional group. Much less effort has been made to imitate the oxidation of
more complex molecules, with a range of functionalities, such as drugs or other
xenobiotics. By varying the structure of the porphyrin, the metal ion, the
oxidant, and the reaction conditions, it is possible to modulate the
regioselectivity of the oxidation reactions. Recently, and along with studies on
the synthesis and reactivity of porphyrins, chlorins, and phthalocyanines, our
group was able to develop an interesting line of research in the field of
biomimetic oxidation of organic compounds using environmentally benign hydrogen
peroxide as oxidant and Mn(III) or Fe(III) porphyrin complexes as catalysts. The
more up to date results obtained in such work are reviewed here.
