The elusive seven-membered cyclic imino ether tetrahydrooxazepine [PDF]
, 2018 Cyclic imino ether heterocycles are used as ligands in transition metal catalysis, in various drugs and as reactive monomers in living cationic ring-opening polymerization (CROP). While five- and six-membered cyclic imino ethers, i.e.

Veterinary Clinical Pathology, Volume 54, Issue 1, Page 15-23, March 2025.Abstract A 6‐year‐old, intact male English Bulldog presented for evaluation of weakness. Physical examination revealed mildly pale mucous membranes and ophthalmologic alterations. A complete blood cell count was performed on the Urit Smart V5 and the Sysmex XN‐1000V, and showed several hematologic discrepancies between the analyzers.

A novel, efficient synthesis of N-aryl pyrroles via reaction of 1-boronodienes with arylnitroso compounds [PDF]
, 2013 A one-pot hetero-Diels–Alder/ring contraction cascade is presented from the reaction of 1-boronodienes and arylnitroso derivatives to derive N-arylpyrroles in moderate to good yields (up to 82%)

Journal of Applied Polymer Science, Volume 142, Issue 7, February 15, 2025.Benzoxazine monomers based on sesamol, paraformaldehyde, and diamines feature a parity effect of used aliphatic diamine with a decrease in melting temperature in case of odd‐numbered diamines. Diaminopentane and ‐hexane yielded polybenzoxazines with good thermal and thermo‐mechanical properties.

A Diversity-Oriented Synthesis Approach to Functionalized Azaheterocycles using Cyclic Alpha-Halo Eneformamides [PDF]
, 2017 Functionalized piperidines, azepanes, azamacrocycles, morpholines, and thiomorpholines are common structural motifs found in a wide range of pharmaceuticals such as carmegliptine, levofloxacin, thioridazine, claviciptic acid, and azithomycin. As a result,

Journal of Chemistry, Volume 2025, Issue 1, 2025.Antibiotic resistance represents a significant public health challenge in the current century. The β‐lactam antibiotics, together with carbapenems, are inactivated by zinc‐dependent bacterial enzymes called metallo‐β‐lactamases (MBLs). Presently there are no clinically permitted MBL inhibitors, and to produce such drugs, it is indispensable to ...

Synthesis of Oxazines by Palladium Catalyzed Reductive Cyclization of Nitroarenes and Dienes Using Phenyl Formate as CO Surrogate [PDF]
, 2018 The synthesis of hetero-Diels-Alder adducts derived from nitrosoarenes as dienophiles (oxazines) has been the focus of much attention in recent years, since these products have pharmacological activity themselves or can be easily transformed into other ...
