Pyridines from azabicyclo[3.2.0]hept-2-en-4-ones through a proposed azacyclopentadienone [PDF]
Pyridines have been formed by heating azabicyclo[3.2.0]hept-2-en-4-ones in toluene. The generation of a 3-azacyclopentadienone intermediate via a [2+2]-cycloreversion is proposed as the key step.

ANTIMICROBIAL ACTIVITY OF 1, 3, 4-OXADIAZOLES: A REVIEW
This review provides readers with an overview of their broad spectrum of pharmacological activities for 1, 3, 4-oxadiazole derivatives, and as reported over the past years. The search for new antimicrobial agents will consequently always remain as an important and challenging task for medicinal chemists.
