The first solid-phase synthesis of 1,4-benzothiazin-3(4H)-ones and 1,4-benzoxazin-3(4H)-ones is reported. Alkylation of the immobilized 4-hydroxy-3-nitrobenzamide 2a and 3-nitro-4-sulfanylbenzamide 2b, followed by reduction and cyclization gave 4. Further alkylation and acylation was performed on th
## Abstract Substituted 2β(benzylamino)β2__H__β1,4βbenzoxazinβ3(4__H__)βones are unstable under alkaline and acidic conditions, undergoing opening of the benzoxazinone ring. 2βBromoβ2__H__β1,4βbenzoxazinβ3(4__H__)βones show similar degradation under alkaline conditions, while replacement of Br at C
