Chemical and Pharmaceutical Bulletin, 2013 A new class of mono and bis heterocycles-styrylsulfonylmethyl 1,3,4-oxadiazoles, pyrazolyl/isoxazolyl-1,3,4-oxadiazoles were prepared and studied their antioxidant activity. The compound methyl substituted 2-(p-methylphenylamino-sulfonylmethyl)-5-[Z-(p-methylstyrylsulfonylmethyl)]-1,3,4-oxadiazole displayed slightly higher antioxidant activity than the

Angewandte Chemie International Edition, EarlyView.We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.
