Functions and properties of native peptides vary from highly specific antibiotics or cytotoxic
antitumor drugs, to hormones, neurotransmitters, immunomodulators, etc. Despite their …

Heterocycles are an extraordinarily important class of compounds, making up more than half
of all known organic compounds. Heterocycles are present in a wide variety of drugs, most …

Particular success has been achieved in the synthesis of new products and in processes
since the twelve principles of “green chemistry” were formulated in the 1990s. These …

Proteinogenic and non-proteinogenic R-amino acids (R-AAs) constitute one of the five most
important families of natural products1 and are essential molecules in many scientific areas …

This review discusses the origins of iodine-mediated oxidation catalysis and gives a
comprehensive overview on this young field of research. The focus is set on oxidative C–X …

The discovery of nonproteinogenic amino acids among natural products, either in native
state or as fragments of complex molecules, has increased the level of interest in this family …

More than a decade ago, the question was raised by Sweeney if aziridines are epoxides'
ugly cousins? 1 The overview on the biological properties, synthetic accessibility, and useful …

Aziridines are saturated three-membered heterocycles containing one nitrogen atom. These
compounds are among the most fascinating intermediates in organic synthesis, acting as …

This review updates the recent developments in asymmetric aziridination using chiral
substrates as well as chiral catalysts, covering the literature since the beginning of 2010. It …

we have reported an asymmetric amine conjugate addition to enones that provides a
suitable platform for developing an unprecedented example of highly chemoand …
