A silver catalyzed and microwave assisted one-pot cascade synthesis provides efficient access to diverse alkaloid-inspired scaffold classes, and a concise and efficient total synthesis of homofascaplysin C and fascaplysin.

Small bioactive molecules are pre-requisite for any discovery discipline. Aware of the fact that bioactivity is not randomly dispersed in the vast chemical space, chemists have been developing hypothesis that can lead them to the islands of bioactivities. Natural products have always been a source of inspiration and their structural motifs provide biologically relevant starting points for library synthesis. In addition to that, Diversity Oriented Synthesis (DOS) and Biology Oriented Synthesis (BIOS) have emerged as tools to guide synthesis design and help enrich compound collections in biological activities. Coherent developments in chem- and bioinformatic tools and in organic synthesis methods targeting efficient generation of compound collections are required to identify interesting molecules that can be employed as chemical probes in chemical biology research and drug candidates in medicinal chemistry investigations.

In discovering the remarkable catalytic properties of BINOL-derived phosphoramidites (binoP-NR(2)), Dutch researchers recently achieved a long-awaited breakthrough in asymmetric catalysis. For the first time, easily accessible monodentate chiral P(III) ligands turned out to provide high enantioselectivities when used in rhodium-catalysed olefin hydrogenation. The simplest ligand representative of this family is MonoPhos, which can be made straightforwardly from BINOL and hexamethylphosphorous triamide. Since the first publication dealing with such catalysts (J. Am. Chem. Soc., 2000), a variety of binoP-NRR' ligands have been reported in which the amino group bears a functional substituent or a stereogenic centre. This critical review examines the impact of the presence of such a functionality in the amino group on catalytic olefin hydrogenation reactions.
