Abstract
In this review, we summarize the origin and advancements of iridium-catalyzed asymmetric allylic substitution reactions during the past two decades. Since the first report in 1997, Ir-catalyzed asymmetric allylic substitution reactions have attracted intense attention due to their exceptionally high regio- and enantioselectivities. Ir-catalyzed asymmetric allylic substitution reactions have been significantly developed in recent years in many respects, including ligand development, mechanistic understanding, substrate scope, and application in the synthesis of complex functional molecules. In this review, an explicit outline of ligands, mechanism, scope of nucleophiles, and applications is presented.

Abstract
Tropanes are an important class of alkaloid natural products that are found in plants all over the world. These compounds can exhibit significant biological activity and are among the oldest known medicines. In the early 19th century, tropanes were isolated, characterized, and synthesized by notable chemical researchers. Their significant biological activities have inspired tremendous research efforts toward their synthesis and the elucidation of their pharmacological activity both in academia and in industry. In this chapter, which addresses the developments in this field since 1994, the focus is on the synthesis of these compounds, and several examples of sophisticated synthetic protocols involving both asymmetric and catalytic approaches are described. In addition, the structures of more than 100 new alkaloids are included as well as the applications and pharmacological properties of some tropane alkaloids.

Abstract
Practical syntheses of 8-oxa-3-aza-bicyclo[3.2.1]octane and 9-oxa-3-aza-bicyclo[3.3.1]nonane, useful intermediates for synthesising kinase inhibitors, were achieved from readily available starting materials, using a solvent-free thermolytic cyclisation for the key step.

Abstract
Sourcing large numbers of lead-like molecules - compounds that would serve as good starting points for drug discovery programmes - is currently very challenging. The concept of lead-oriented synthesis has recently been articulated to capture the specific problem of preparing diverse small molecules with lead-like molecular properties. In this Feature, some methods that might be used to prepare lead-like molecular scaffolds are described, and presented in the context of diversity-oriented synthetic strategies that allow wide variation in molecular scaffold. It is concluded that the development of a wider toolkit of reactions that is reliable with more polar substrates will be required to allow genuine combination of molecular scaffold within lead-like chemical space.

A preparatively accessible route to a series of conformationally-locked bicyclic morpholines has been developed. This flexible approach allows for diversification in order for a small array of lead-like scaffolds to be synthesised from readily available key building blocks.
