Chiral t-Boc protected propargylic amines have been obtained starting from aminoaldehydes derived from natural aminoacids. Stannylcupration of these substrates affords an easy regio- and stereocontrolled route to the corresponding γ-stannylated (E)-allylamines which are useful intermediates for the synthesis of the corresponding γ-funtionalized allylic systems.
Secondarystructures tend to be recognizable because they have repeating structural motifs, but mimicry of these does not have to follow such well‐defined patterns. Bioinformatics studies to match side‐chain orientations of a novel hydantoin triazole chemotype (1 ) to protein‐protein interfaces revealed it tends to align well across parallel and antiparallel sheets, like rungs on a ladder.

The Cu(I)-catalyzed cycloaddition of alkynes and azides (click reaction) provides a robust method for the construction of macrocyclic small molecules via an intramolecular macrocycloaddition. A three-subunit system has been used to explore the tolerance of this macrocycloaddition to variations of stereochemistries and substituents.
