Flexible access to conformationally-locked bicyclic morpholines [PDF]
, 2013 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 ...

The Journal of Physical Chemistry A, 2018 The density functional theory method was employed to calculate three-dimensional structures for a series of novel explosophores. The design of new molecules (DA1-DA12) was based on the bridge-ring structures that could be formed via Diels-Alder (DA) reaction of selected nitrogen-rich dienes and tetranitroethylene dienophile.

Use of metal catalysts bearing Schiff base macrocycles for the ring opening polymerization (ROP) of cyclic esters [PDF]
, 2017 © 2017 by the authors. Schiff base macrocycles are emerging as useful scaffolds for binding two or more catalytic metals in close proximity. Such coordination chemistry allows for the evaluation of potentially beneficial catalytic cooperative effects. In
