Conversion of 3-nitroanilines into tricyclic systems: 1H-1-alkyl-8-X-2,2-dioxoisothiazolo[5,4,3-d,e]quinolines
摘要:
The route leading to the tricyclic 2,2-dioxoisothiazolo[5,4,3-d,e]quinolines from 3-nitroanilines has been described. The scope and limitation factors as well as some mechanistic features are discussed. (C) 2001 Elsevier Science Ltd. All rights reserved.
