Abstract: | Heterocycles from Enamines Aminoacrylderivatives ( 1 ) and Br2/NH4SCN form iminothiazolinones 3a–c and with chlorosulfonylisocyanate thiadiazinonedioxide 8 . Reaction of 3 a with hydrazine yields disulfide 6 . Compound 2 and PCl3 yield diazaphosphorines 7a–c . By reaction of pyrimidinone 9 with NaOCl, HCl/H2O2 or Br2/NH4SCN dichloropyrimidinone 10 , dichlorooxaziridine 16 , and thiocyanate 13 are formed. Octahydroquinazolinone ( 17 ) and NaOCl or H2O2/HCl form chloroderivatives 18, 19 and 20, 18 with peracid oxaziridine 22 . Compounds 16, 21, 22 and 13 with NaOCl form N-chloroderivatives 23, 24, 25 and 26 resp. |
