Abstract

(5) HPLC analysis (column prepacked with LiChrosorb-Si 60, 25 X 0.45 cm, n-hexanelethyl acetate (85/15), 2 mL min-') revealed the presence of only one, narrow peak with K'= 3.1. However,'H NMR analysis revealed the presence of two isomeric compounds, the ketophenol form (3h) and the 2-chromanol form (4h), with the isomeric ratio 3h/4h varying with the solvent used: typically 72/28 (MeOD), 75/25 (CDCI,), and 63/37 (CCl,). The keto- ...
