Syntheses and Reactions of Thiadiazolopyrimidinone Derivatives
Tsuji, Tadakazu
, p. 489 - 492 (2007/10/02)
5-Imino-6H-7-one, 7-amino-5-one and 5-isocyano-7-one derivatives of thiadiazolo- and -thiazolopyrimidines were synthesized. 5-Isocyano-7-one derivatives were obtained by the reaction of the corresponding 5-imino-6H-7-ones with the Vilsm
