A. Asmanidou et al., Spiro cyclohexadienones from the reaction of phenolic enaminone derivatives with hypervalent iodine reagents, MOLECULES, 5(6), 2000, pp. 874-879
Phenolic enamino compounds, prepared from 2-(4-hydroxyphenyl)-ethylamine an
d the corresponding beta-keto carbonyl compounds, afford spiro cyclohexadie
none derivatives on reaction with hypervalent iodine reagents.
