o-Nitroaniline Derivatives - 13 reactions of N-(o-nitroaryl)sarcosine esters with bases
Autor: M. D. Mcfarlane, Raymond K. Mackie, David M. Smith, Pamela A. Collins
Publikováno v: Tetrahedron. 48:7887-7898
The title reactions give 1-hydroxy-4-methylquinoxaline-2,3-diones ( 4 ) together with a variety of mono- and bi-cyclic by-products. All of these may result from a common intermediate, viz . a 1-hydroxy-4-methyl-3,4-dihydro-1 H -2,1,4-benzoxadiazine-3
