DOI: 10.1002/chir.23316
Abstract: The interrelation between the configurational lability of nitrogen and sulfur atoms within the -NH-SO2 group of some thiazine sulfonamides is discussed. We have found that the compounds of the above series can crystallize as various… read more here.

DOI: 10.1021/acs.orglett.1c03237
Abstract: Crystallization-Induced Diastereomer Transformation (CIDT) of α-bromo-α'-(R)-sulfinylketones is reported. This process provides not readily accessible enantiopure stereolabile α-bromoketones, which after diastereoselective carbonyl group reduction lead to the corresponding highly value-added anti and syn-bromohydrins with excellent diastereoselectivities.… read more here.

DOI: 10.1039/c7ra08811f
Abstract: A green and highly stereoselective method for the synthesis of cis or trans-1,3-disubstituted-tetrahydro-β-carbolines has been developed using water as the solvent. A mixture of cis and trans-1,3-disubstituted-tetrahydro-β-carboline hydrochlorides can be converted to a single cis… read more here.

DOI: 10.1039/c9dt01910c
Abstract: Luminescent Cu(i) iodide complexes featuring simple neutral diimine and phosphine ligands were prepared. The emission intensity of these complexes was significantly enhanced by crystallization. Intermolecular π-π interactions between the adjacent diimine ligands should be responsible… read more here.

DOI: 10.3390/ijms23084206
Abstract: Here, we report a design strategy for constructing supramolecular organic frameworks by introducing 1H-pyrazole groups to aromatic cores as non-coplanar molecules to form diverse supramolecular assemblies through multiple 1H-pyrazole [N−H···N] hydrogen bonds as well as… read more here.
