T. Itoh et al., DEAMINATION OF 2-AMINOTHIAZOLES AND 3-AMINO-1,2,4-TRIAZINES WITH NITRIC-OXIDE IN THE PRESENCE OF A CATALYTIC AMOUNT OF OXYGEN, Chemical and Pharmaceutical Bulletin, 45(9), 1997, pp. 1547-1550
2-Aminothiazoles, 2-aminobenzazoles, and 3-amino-1,2,4-triazines were
deaminated using nitric oxide (NO) in the presence of a catalytic amou
nt of oxygen to afford corresponding unsubstituted heterocycles in goo
d yields.
