Reactions of Furazanoquinoxalines with Phosphorus Ylides and an Unusual Oxidative Transformation of the Transylidation Product

Reactions of furazanoquinoxalines 1 with phosphorus ylides 2 afford the transylidation product 3 and/or 4,9-dihydrofurazanoquinoxalines 4.Oxidation of 3 with phenyliodide bis-trifluoroacetate gave the fused furan derivative 13 in high yield.

Reactions of Stable Wittig Reagents with Episulfides

Stable Wittig reagents effectively reacted with episulfides to afford dialkyl fumarates and maleates in good yields.The reaction probably occured via attack of the ylide carbanion on episulfide's sulfur to form a thiocarbonyl intermediate.The ylide further attacked this thiocarbonyl intermediate to give the final olefins.

REACTIONS OF FUROXANS WITH PHOSPHORUS YLIDES

Benzofuroxan (1) reacts with phosphorus ylide 2 to give benzimidazole derivatives 8 and 10, whereas reaction of 1 with ylide 12 furnishes quinoxaline 17 via an initial Wittig-type reaction.Similarly the reaction between the furoxanoquinoxalines 19a or 19b and the ylide 2 yielded compounds 22a and 22b, respectively.In these reactions as well as in the reactions of the above furoxans with other phosphorus ylides, a significant deoxygenation of the furoxans to furazans with subsequent oxidation of the ylides is generally observed.
