Procedure

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.
