Rodriguez-Morgade,Torres,Vazquez
, p. 1235 - 1238 (2007/10/02)
The reaction of [2,1]benzisoxazole-4,7-quinones 1 and naphth[2,3c]isoxazole-4,9-quinone 4 with phosphines leads to phosphoranylideneaminoquinones 2 and 5, respectively, in good to excellent yields.
Rearrangement of 3-Methoxy Substituted Benzisoxazole- and Naphthisoxazolequinones in Dimethyl Sulfoxide Solution
Torres, Tomas,Eswaran, S.V.,Schaefer, Wolfram
, p. 705 - 711 (2007/10/02)
The reactions of the 3-methoxy-isoxazole quinones 1 and 9 in a highly polar solution of dimethyl sulfoxide have been studied.Quinones of type 2,4/11,5/12,6 and 7/13 have been isolated; nmr measurements give a detailed insight into the reaction mechanism.
Quninone Chemistry. Synthesis of 3-Dialkylsulfoximido- and 2-Dialkylsulfimido-3-carbomethoxy-1,4-benzo- and Naphthoquinone Derivatives
Torres, Tomas,Eswaran, S.V.,Schaefer, Wolfram
, p. 701 - 704 (2007/10/02)
3-Methoxybenzisoxazole-4,7-quinones 1 and naphthisoxazole-4,9-quinone 4 react with dimethyl sulfoxides to give sulfoximidoquinones 2 and 5, sulfimidoquinones 8 and 11 respectively as major products.
Quninone Chemistry. Synthesis of 3-Methoxybenzisoxazole- and 3-Methoxynaphthisoxazolequinones
Torres, Tomas,Eswaran, S.V.,Schaefer, Wolfram
, p. 697 - 699 (2007/10/02)
Benzisoxazole-4,7-quinones 4 are prepared by an improved method using oxidative amination of 1 to give 2, followed by amine exchange to 3 and cyclization with lead tetraacetate.Naphthisoxazole-4,9-quinone 7 is obtained from 5 by an analogous procedure.
