T. Yasunaga et al., A FACILE AND PRACTICAL PROCEDURE FOR THE SYNTHESIS OF 8-HYDROXY-4-OXOCHROMAN DERIVATIVES, Synthetic communications, 27(24), 1997, pp. 4245-4253
Novel 8-hydroxy-4-oxochroman derivatives were prepared from appropriat
e 4-chromanones via the Baeyer-Villiger oxidation followed. by an intr
