Synthesis of lyngbic acid 1a: To a solution of 4-methoxyundec-1-ene (460 mg, 2.5 mmol) and 4-pentenoic acid 6 (0.051 mL, 0.5 mmol) in dichloromethane (5 mL) was added second generation Grubbs' catalyst (11 mg). The mixture was heated to 40 °C for 7 h. A second portion of Grubbs' catalyst was then added and the mixture was kept warm for 16 h. The solvent was evaporated under reduced pressure and the residue was purified by flash-chromatography on silica (hexanes/AcOEt = 90/10). Acid 1a was obtained as a colorless oil (108 mg, 84%).

Preparation of (S)-undec-1-en-4-ol 7: To a solution of camphor-derived allylic alcohol (9.6 g, 50 mmol) and camphor sulfonic acid (395 mg, 1.7 mmol) in dichloromethane (17 mL), was added octanal (2.13 g, 16.6 mmol). The solution was stirred at room temperature for 18 h then concentrated under reduced pressure. The residue was purified by flash-chromatography on silica (hexanes/AcOEt, 95/5) to give 7 as a colorless liquid (2.02 g, 72%, 86% ee).

To a solution of (S)-undec-1-en-4-ol (60 mg, 0.35 mmol) in dichloromethane (3.5 mL) was added at 0 °C, (S)-2-phenyl propionic acid (58 mg, 0.39 mmol), 4-dimethylaminopyridine (12 mg, 0.1 mmol), and 1,3-dicyclohexylcarbodiimide (80 mg, 0.39 mmol). This solution was stirred 18 h at room temperature, filtered through cotton, and purified on silica. The desired ester was obtained as a colorless oil (103 mg, 97%).
