5-Phenyl-1,3,4-oxadiazol-2-amine [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2012
In the title complex, C(8)H(7)N(3)O, the C-O [1.369 (2) and 1.364 (3) Å] and C=N [1.285 (3) and 1.289 (3) Å] bond lengths in the oxadiazole ring are each almost identical within systematic errors, although different substituents are attached to the ring. The phenyl ring is inclined to the planar oxadiazole ring [r.m.s. deviation 0.002 Å] by 13.42 (18)°.

In Silico, In Vitro, and In Vivo Antinociceptive Potential of S‐Naproxen Derivatives

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
Selected naproxen derivatives were investigated for their antinociceptive effects, using in vitro (COX‐I/COX‐II antagonistic effect), in vivo (acetic acid and hot plate assay), and in silico (molecular simulation studies) approaches. The COX inhibition studies revealed that the maximum percent effect exhibited by GMO‐I‐111a 96.01 and 92% against COX‐2 ...

Radical Retrosynthesis of Natural Products Enabled by Iron‐Based Reductive Olefin Coupling

open access: yesAngewandte Chemie Novit, Volume 2, Issue 1, March 2026.
This review highlights iron‐catalyzed reductive olefin coupling (ROC)—a strategy for C─C bond formation driven by metal‐hydride hydrogen atom transfer (MHAT)—as a key tool in natural products synthesis. This review surveys dozens of total syntheses employing ROC‐based strategies, highlighting its power to forge strained rings, quaternary centers, and ...
