Abstract

1,2,3-Oxadiazole 3-oxides with an alkoxymethyl group at the 5-position were reduced by reacting them with sodium borohydride to produce 4,5-dihydro-1,2,3-oxadiazole 3-oxides in good yields, which were further transformed into substituted diazene N-oxides by reacting with Grignard reagents.
