Abstract Synthesis of hydroxyimino-N-acetamides 8 (monoximes) in good yields from Ν´1, Ν´2-dihydroxy- Ν1, Ν2-diimidamides 7 (dioximes) and oxidation effords of compounds 7 and 8 to oxadiazoles, with lead tetraacetate, potassium ferricyanide, phenyl-diacetoxyiodine and IBX. The reaction of o-quinone 120 (which was prepared from hydroxy-p-benzoquinone 117) with ylide 46 afforded the coumarine derivatives 102i and 103i. The compound 103i is further transformed into compounds 104, 105 and 106 with N-bromosuccinimide.
