Pd-catalyzed C-N coupling of primary (het)arylamines with 5-substituted 3-chloro-4 H -1,2,6-thiadiazin-4-ones
摘要:
The Buchwald-Hartwig Pd-catalyzed C-N coupling reaction of 5-substituted 3-chloro-4H-1,2,6-thiadiazin-4-ones with primary (het)arylamines is described, affording twenty new 3,5-disubstituted 4H-1,2,6-thiadiazin-4-ones in 56-99% yield. The protocol enables the mild preparation of difficult to access 3,5-dianilino-1,2,6-4H-thiadiazin-4-ones. The reaction scope and limitations are discussed. (C) 2018 Elsevier Ltd.
