Bouvy, A.,Janousek, Z.,Viehe, H. G.,Arietta, J. M.
, p. 869 - 872 (2007/10/02)
Ynediamine 1 is a versatile synthon in heterocyclic chemistry.It reacts with arylisocyanates to furnish new diaminoquinolones 4 and 5 by rearrangement as confirmed by X-Ray measurements.They react with phosgene by loss of methyl chloride whereby an oxazolone ring is formed.
