Vj. Ram et al., RING TRANSFORMATION REACTION .2. REACTION SPECIFICITY OF HYDRAZINES TOWARDS ARYL-4-(METHYLTHIO)-2-OXO-2H-PYRAN-3-CARBONITRILES AND CORRESPONDING 3-ETHYL CARBOXYLATE, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 32(9), 1993, pp. 924-928
Reaction specificity of hydrazine hydrate, cyclohexyl- and phenyl-hydr
azines towards 6- or 5,6-disubstitued -4-(methylthio)-2-oxo-2H-pyran-3
-carbonitriles and the corresponding 3-ethyl carboxylate (1,8)has been
studied.
