Popis:	(0.66 g, 2.8 mmol) and 3-methyl-2-butenal (0.47 g, 5.6mmol) in methylene chloride (20 mL) was added ethylene-diamine diacetate (0.10 g, 0.6 mmol) at room temperature.The reaction mixture was stirred at room temperature for 12h. Water (50 mL) was added and the solution was extractedwith methylene chloride (3 × 50 mL). Evaporation of solv-ent and purification by column chromatography on silica gelusing hexane/ethyl acetate (10:1) gave
