And the article was published in Molecules in 2013. Category: chlorides-buliding-blocks The author mentioned the following in the article:

The dynamic atroposelective resolution of chiral salts derived from oily racemic nicotinamides (RS)-I (R = pyrrolidino, piperidino, morpholino) and enantiopure dibenzoyltartaric acid (DBTA) was achieved by crystallization The absolute structures of the axially chiral nicotinamides were determined by X-ray structural anal. The chirality could be controlled by the selection of enantiopure DBTA as a chiral auxiliary. The axial chirality generated by dynamic salt formation was retained for a long period after dissolving the chiral salt in solution even after removal of the chiral acid. The rate of racemization of nicotinamides could be controlled based on the temperature and solvent properties, and that of the salts were prolonged compared to free nicotinamides, as the mol. structure of the pyridinium ion in the salts was different from that of acid-free nicotinamides. In the experimental materials used by the author, we found 2-Chloro-4,6-dimethylnicotinic acid(cas: 66662-48-4Category: chlorides-buliding-blocks)

We report the synthesis of a degradable polyphosphoramidate via ring-opening metathesis polymerization (ROMP) with the Grubbs initiator (IMesH2)(C5H5N)2(Cl)2Ru = CHPh. Controlled ROMP of a low ring strain diazaphosphepine based cyclic olefin was achieved at low temperatures to afford well-defined polymers that readily undergo degradation in acidic conditions via the cleavage of the acid-labile phosphoramidate linkages. The diazaphosphepine monomer was compatible in random and block copolymerizations with Ph and oligo(ethylene glycol) bearing norbornenes. This approach introduced partial or complete degradability into the polymer backbones. With this chem., we accessed amphiphilic poly(diazaphosphepine-norbornene) copolymers which could be used to prepare micellar nanoparticles.
