Abstract
Myoglobin was subjected to site-directed mutagenesis and transformed into a catalyst able to perform atom transfer radical cyclisation reactions, i.e. intramolecular atom transfer radical additions. Replacing the iron-coordinating histidine with serine, or introducing small changes inside or at the entrance of the active site, transformed the completely inactive wild-type myoglobin into an artificial metalloenzyme able to catalyse the 5-exo cyclisation of halogenated unsaturated compounds for the synthesis of γ-lactams. This new-to-nature activity was achieved not only with purified protein but also in crude cell lysate and in whole cells.

Abstract
Gold-catalyzed cycloisomerization of propargyl pyruvates has been developed as a key reaction to prepare maleic anhydride-type natural products. By combining with chemoselective epoxidation of the formed γ-alkylidenebutenolides and oxidative cleavage of epoxides, the first synthesis of tricladolide D and racemic tricladolide C has been achieved in 52 and 16% overall yields with five to seven steps starting from commercially available compounds. Further catalytic hydrogenation of alkenylated maleic anhydrides derived from γ-alkylidenebutenolides produced chaetomellic anhydride A (19% yield for six steps) and tyromycin A (15% yield for six steps), which provides flexible synthetic approaches to these naturally occurring dialkylated maleic anhydrides distinct from the documented ones.

Abstract
This review summarizes the current status of transition metal catalyzed reactions involving radical intermediates in organic chemistry. This part focuses on radical-based methods catalyzed by group 10 and group 11 metal complexes. Reductive and redox-neutral C-C bond formations catalyzed by low-valent metal complexes as well as catalytic oxidative methods are reviewed. Catalytic processes which rely on the combination of two metal complexes are also covered.

Abstract
A copper-catalyzed methodology to functionalize remote sp(3) C-H bonds in alkyl hydroperoxides is presented. The atom-transfer chlorination utilizes simple ammonium chloride salts as the chlorine source, and the internal redox process requires no external redox reagents.

Abstract
A lot of attention is currently being paid to the transition to a biobased economy. In this movement, most efforts concentrate on the development of bioenergy applications including bioethanol, biodiesel, thermochemical conversion of biomass, and others. However, in the energy sector other nonbiomass alternatives are known, whereas no valuable alternatives are available when thinking about chemical building blocks. Therefore, it is also essential to develop new routes for the synthesis of bio-based chemicals and materials derived thereof. Such intermediates can originate either from plants or from animals. Castor oil is a non-edible oil extracted from the seeds of the castor bean plant Ricinus communis (Euphorbiaceae), which grows in tropical and subtropical areas. Globally, around one million tons of castor seeds are produced every year, the leading producing areas being India, PR China, and Brazil.2 10-Undecenoic acid or undecylenic acid is a fatty acid derived from castor oil that, owing to its bifunctional nature, has many possibilities to develop sustainable applications.
