Heckmann, C.M. (author), Bürgler, Moritz (author), Paul, C.E. (author)The unmatched chemo-, regio-, and stereoselectivity of enzymes renders them powerful catalysts in the synthesis of chiral active pharmaceutical ingredients (APIs). Inspired by the discovery route toward the LPA<sub>1</sub>-antagonist BMS-986278, access to the API building block (1S,3R)-3-hydroxycyclohexanecarbonitrile was envisaged using an...journal article 2024

Biocatalytic Aromaticity-Breaking Epoxidation of Naphthalene and Nucleophilic Ring-Opening ReactionsZhang, W. (author), Li, Huanhuan (author), Younes, S.H.H. (author), Gómez De Santos, Patricia (author), Tieves, F. (author), Grogan, Gideon (author), Pabst, Martin (author), Alcalde, Miguel (author), Whitwood, Adrian C. (author), Hollmann, F. (author)Aromatic hydroxylation reactions catalyzed by heme-thiolate enzymes proceed via an epoxide intermediate. These aromatic epoxides could be valuable building blocks for organic synthesis giving access to a range of chiral trans-disubstituted cyclohexadiene synthons. Here, we show that naphthalene epoxides generated by fungal peroxygenases can...journal article 2021

Yayci, Abdulkadir (author), Baraibar, Álvaro Gómez (author), Krewing, Marco (author), Fernandez Fueyo, E. (author), Hollmann, F. (author), Alcalde, Miguel (author), Kourist, Robert (author), Bandow, Julia E. (author)Peroxidases and peroxygenases are promising classes of enzymes for biocatalysis because of their ability to carry out one-electron oxidation reactions and stereoselective oxyfunctionalizations. However, industrial application is limited, as the major drawback is the sensitivity toward the required peroxide substrates. Herein, we report a...journal article 2020

Yayci, Abdulkadir (author), Dirks, Tim (author), Kogelheide, Friederike (author), Alcalde, Miguel (author), Hollmann, F. (author), Awakowicz, Peter (author), Bandow, Julia E. (author)The use of a microscale atmospheric pressure plasma jet (μAPPJ) was investigated for its potential to supply hydrogen peroxide in biocatalysis. Compared to a previously employed dielectric barrier discharge (DBD), the μAPPJ offered significantly higher H<sub>2</sub>O<sub>2</sub> production rates and better handling of larger reaction volumes....journal article 2020
