3-Methoxyphenol can be selectively nitrosated in propionic acid, and the resulting slurry of 2-nitroso-5-methoxyphenol can be cleanly oxidized by nitric acid to the nitro compound. An improved procedure for the preparation of 6-methoxy-2(3H)-benzoxazolone
Completion of the spectroscopical data for the synthesis of DIMBOA

Cyclic hydroxamic acids like 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin- 3(4H)-one (DIMBOA) and 2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one (DIBOA) are found in several plants playing an important role in the defense-system of plants against a variety of enemies. To investigate new mechanism and effects we synthesized the molecules using known synthetic pathways. Since the chemical data of DIMBOA are not complete or even false, we decided to publish the missing ones in this journal. O?sterreichische Apotheker-Verlagsgesellschaft m. b. H.
A facile access to substituted 2-nitrosophenols and 2-nitrophenols via regioselective nitrosation of resorcinol monoethers

Solid sodium nitrite in anhydrous propionic acid is an effective system for regioselective nitrosation of the subject compounds. High yields of pure 2-nitroso products are obtained rapidly and efficiently. Attack at the 4-position becomes competitive if water is present in the medium. The 5-alkoxy (but not the 3,5-dialkoxy)-2-nitrosphenols can be easily oxidized with nitric acid to yield the corresponding 2-nitro compounds.
