    • 4OH (25%, 6 mL, 42 mM); the resulting solution having pH 10.8. The mixture was shaken for 12 h at room temperature until 1 had completely disappeared then lyophilized and subjected to column chromatography on Toyopearl HW40F (Tosoh Corp., 3 × 47 cm) in water, yielding pure 2 (85 mg) and 3 (36 mg).
