ABSTRACT

Kurt Faber, a synthetic organic chemist by training, strongly influenced the field of biocatalysis throughout the course of his four-decade career (from the late 1980s to the early 2020s). The evolution of his career has gone hand in hand with the development of biocatalysis into a mature and versatile discipline originally deep-rooted in organic chemistry that quickly integrated techniques from molecular biology. His work has provided numerous grounds for recognizing natural catalysts as essential tools in organic synthesis, complementing the more chemical approaches. An important aspect of Kurt Faber's career encompasses teaching, mentoring, and encouraging the development of younger scientists worldwide. His book, Biotransformations in Organic Chemistry, now in its seventh edition, has become a recognized tool for training generations of chemists and biotechnologists and remains a reference worldwide. At Biotrans 2021, the 15th International Symposium on Biocatalysis and Biotransformations (originally scheduled to be held in Graz, Austria, and eventually held online due to the COVID-19 pandemic), Kurt Faber received the Biotrans senior award in recognition of his innovative contributions to the field. In this Account, we would like to acknowledge his contributions to the field of biocatalysis, highlighting both the growing importance of this discipline in many (industrial) sectors and the profound changes that have occurred in recent decades, while reflecting on some of Kurt Faber's most important discoveries and his legacy to this field. © 2022 The Authors.

ABSTRACT

Viral infections cause many severe human diseases, being responsible for remarkably high mortality rates. In this sense, both the academy and the pharmaceutical industry are continuously searching for new compounds with antiviral activity, and in addition, face the challenge of developing greener and more efficient methods to synthesize these compounds. This becomes even more important with drugs possessing stereogenic centers as highly enantioselective processes are required. In this minireview, the advances achieved to improve synthetic routes efficiency and sustainability of important commercially antiviral chiral drugs are discussed, highlighting the use of organocatalytic methods.

ABSTRACT

Amino acids (AAs) play an important role in the modern health industry as key synthetic precursors for pharmaceuticals, biomaterials, biosensors, and drug delivery systems. Currently, over 30% of small-molecule drugs contain residues of tailor-made AAs or derived from them amino-alcohols and di-amines. In this review article, we profile 12 AA-derived new pharmaceuticals approved by the FDA in 2020. These newly introduced drugs include Tazverik (epithelioid sarcoma), Gemtesa (overactive bladder), Zeposia (multiple sclerosis), Byfavo (induction and maintenance of procedural sedation), Cu 64 dotatate, and Gallium 68 PSMA-11 (both PET imaging), Rimegepant (acute migraine), Zepzelca (lung cancer), Remdesivir (COVID-19), Amisulpride (nausea and vomiting), Setmelanotide (obesity), and Lonafarnib (progeria syndrome). For each compound, we describe the spectrum of biological activity, medicinal chemistry discovery, and synthetic preparation.

ABSTRACT

A nickel-catalyzed asymmetric reductive hydroarylation of vinyl amides to produce enantioenriched α-arylbenzamides is reported. The use of a chiral bisimidazoline (BIm) ligand, in combination with diethoxymethylsilane and aryl halides, enables the regioselective introduction of aryl groups to the internal position of the olefin, forging a new stereogenic center α to the N atom. The use of neutral reagents and mild reaction conditions provides simple access to pharmacologically relevant motifs present in anticancer, SARS-CoV PLpro inhibitors, and KCNQ channel openers.
