実験手順: Compound XXXI was prepared as described in Scheme I from 10-undecen-1-ol, 1, by a three step procedure in an overall yield of 31%. Alkylation of phthalimide with alkanol, 1, under Mitsunobu conditions, followed by reaction with hydrazine gave 1-aminoundec-10-ene, 2, in 66% yield. The amine was derivatized with O-acetylsalicyloyl chloride and the resulting alkene, 3, was oxidized to the acid using potassium permanganate. Removal of the acetate, followed by acid precipitation provided compound XXXI in 47% yield based on amine 2. ##STR65##

実験手順: A solution of commercially available 1-aminoundec-10-ene (1 g) dissolved in ethyl formate (3.5 mL) was kept at 50° during 3 h. Evaporation of the solvent yielded 1.18 g of N-formyl-1-aminoundec-10-ene (yield: 99%). Evaporation of the solvent

実験手順: Commercially available 11-aminoundec-1-ene (1 g) is dissolved in ethyl formate (1.5 ml). The reaction mixture is kept at 50° C. for 3 h. Then, evaporation of the liquid phase under vacuum furnished almost quantitatively N-formyl-11-aminoundec-1-ene (1.18 g). To a stirred solution of the latter (0.5 g) in chloroform (1 ml) and pyridine (0.2 ml) is added dropwise a solution of dibromide in chloroform (2M, 1.4 ml). During addition the temperature of the mixture is maintained at 0° C. The solution is kept at 0° C. during 30 min. then diluted with dichloromethane (10 ml) and washed with saturated solutions of sodium bicarbonate (10 ml), 10% HCl (2×10 ml) and 10% sodium bisulfite (2×10 ml) successively. The organic layer is evaporated to dryness under vacuum and the solid residue is chromatographed over a silica gel column (eluent: hexane/acetone 1:1). This furnished 639 mg of pure N-formyl-10,11-dibromoundecylamine (yield 70%). Then, evaporation of the liquid phase under vacuum
