Abstract Novel amino‐acid‐derived phthalazine reagents have been designed and synthesized for the enantioselective fluorocyclizations of prochiral indoles. The scope reaction is evidenced by 28 examples fluorinated furoindole pyrroloindole heterocycles bearing various functionalities with up to 99% ee. resulting enantioenriched products are found be potent AChE inhibitors. Advantages current new chiral include ease in synthesis analogues readily tunable steric/electronic demands. magnified image
Abstract We apply a chiral anionic phase‐transfer system for the catalytic asymmetric bromoaminocyclization and bromocycloetherification of momo‐functional benzo‐cyclic alkenes. Various brominated tricyclic benzo‐heterocycles were produced with up to 99% yields enantiomeric excess. The resulting enantioenriched hexahydro‐benzoindoles are key building blocks bioactive molecules. magnified image
End-tidal carbon dioxide (P(ET)CO₂) monitoring has become an important tool in clinical monitoring, but there are still limitations practice. Low-frequency modulation was used to reliably acquire respiratory information. Then the disturbances of humidity and flow rate were removed by signal decomposition. Finally, real-time concentration CO₂ calculated displayed adjusted calibration function. Targeted experiments confirm that a period 180 ms depth 50% optimal choice. In this case, effects...

The cation and the anion of title complex, [Cu(CHO2)(C12H8N2)2]BF4 or [Cu(phen)2HCOO]BF4 (phen = 1,10-phenanthroline), both lie on crystallographic twofold rotation axes. CuII ion is in a distorted square-pyramidal geometry, coordinated by four N atoms from two chelating phen ligands one O atom formate ligand. A axis causes H ligand to be disordered.
The molecular structure of the title compound, C13H17NO4, has no symmetry plane because one C atom ethyl group lies out defined by other non-H atoms. In crystal structure, molecules stack along a axis. Symmetry-related are linked C—H⋯O hydrogen bond, forming zigzag chains extending in b-axis direction.
Molecules of the title compound, C12H26N4S2, have 2/m symmetry. Intramolecular N—H⋯N and N—H⋯S hydrogen bonds are observed.
