Analytical Formulas of Molecular Ion Abundances and N2H+ Ring in Protoplanetary Disks [PDF]
, 2015 We investigate the chemistry of ion molecules in protoplanetary disks, motivated by the detection of N$_2$H$^+$ ring around TW Hya. While the ring inner radius coincides with the CO snow line, it is not apparent why N$_2$H$^+$ is abundant outside the CO ...

An unexpected ring formation in morphine chemistry
Arkivoc, 2001 Reaction of (7R)-N-benzyl-N-nor-7-bromoneopinone dimethyl acetal (2) with primary or secondary amines (RNH2, R1R2NH) resulted in 9-amino-substituted hasubanan derivatives; in particular, modification of the 9-(2-hydroxyethyl)amino derivative in subsequent steps gave products 8 with a 9-(oxazolidin-2'-one-3'-yl) substituent.

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

NeoPHOX – a structurally tunable ligand system for asymmetric catalysis
Beilstein Journal of Organic Chemistry, 2016 A synthesis of new NeoPHOX ligands derived from serine or threonine has been developed. The central intermediate is a NeoPHOX derivative bearing a methoxycarbonyl group at the stereogenic center next to the oxazoline N atom.

Organic molecules in the protoplanetary disk of DG Tau revealed by ALMA [PDF]
, 2019 Planets form in protoplanetary disks and inherit their chemical compositions. It is thus crucial to map the distribution and investigate the formation of simple organics, such as formaldehyde and methanol, in protoplanetary disks.
