Abstract: Abstract Six novel bridge-functionalized bisimidazolium bromides have been synthesized for the catalytic cycloaddition of CO2 (70 °C, 0.4 MPa CO2). Additionally, the influence of the hydrogen-bond donors, the N-wing-tip-substituents and the chain length of the connecting carbon… read more here.

Abstract: Azabicyclo[2.1.1]hexanes (aza-BCHs) and bicyclo[1.1.1]pentanes (BCPs) have emerged as attractive classes of sp3-rich cores for replacing flat, aromatic groups with metabolically resistant, three-dimensional frameworks in drug scaffolds. Strategies to directly convert, or "scaffold hop", between these… read more here.
