Cyclic amine ring expansion Aza-heterocycles with rings of more than 6 members are underrepresented in medicinal chemistry owing to challenges with their synthesis. Now, the conversion of 5- and 6-membered saturated cyclic amines into 7- and 8-membered aza-heterocycles can be achieved via a rin...

the ring-closed form provides the stabilized quinonoid structure upon condensation with L-alanine (an amino acid), and deprotonation of the aldimine α-hydrogen. Thus, treatment of L-alanine with ring-opened isomer resulted in poor racemization reaction (3% yield), whereas an increase in the rat...
The intermediately formed enamine of propionaldehyde and proline was selectively reacted with nitrosobenzene. The resulting α-oxoaldehyde represents again a 1,2-difunctional compound (Eq. 2, Scheme 37) [17]. The last example—the organocatalyzed approach to chiral epoxides—was realized by an “...

Benzene is a genotoxic carcinogen with no safe level of exposure. Here, by creating and decorating a structural defect in a metal–organic framework to form MIL-125-Zn, a benzene uptake of 7.63 mmol g–1at 1.2 mbar is observed due to binding to Zn(II) sites. ...
Fe-BTC (BTC = 1,3,5-benzenetricarboxylate) is a nanocomposite MOF, known for its catalytic properties, comprising crystalline nanoparticles and an amorphous matrix. Here, we use scanning electron diffraction to first map the crystalline and amorphous components to evaluate domain size and then...
