Oximes azodicarboxylate

Benzisoxazoles and isoxazoles are also accessible in excellent yields by intramolecular Mitsunobu reaction or related reactions of o-hydroxy- or a-hydroxyoximes ° . Thus, treatment of oxime 208 in the presence of diethyl azodicarboxylate (DEAD) and PPhs in THE leads to benzisoxazoles 209 (equation 91). ... [Pg.262]

The oxime (611) when reacted with ethyl chloroformate undergoes cyclocondensation to form the dihydroquinoxaline (612) the latter is aromatized on treatment with diethyl azodicarboxylate (73LA190). [Pg.725]

When treated with benzoic acid in the presence of triphenylphosphine and diethyl azodicarboxylate, benzophenone oxime gave a high yield of f -benzoylbenzanilide (14), formed via rearrangement of the intermediate 0>benzoyloxime (15). Reaction of p>medioxyaGetophenone oxime with l,rsubstituted derivative (l ), whereas in the presence of allyl bromide... [Pg.692]
