Abstract
The synthesis of a Miltochrista calamine sex pheromone and its diastereomer has been developed. The key steps of the synthetic approach involved Evans’ chiral auxiliaries and the addition of alkyne to aldehyde, which were firstly applied to prepare this sex pheromone and its diastereomer. The synthetic sex pheromone could be used to trap insects and study physiological and ecological questions of the lichen moth.

After being cooled to –78 °C, n-butyllithium (1.34 mL, 2.4 M in THF, 3.21 mmol) was then added over 15 min via syringe pump. The resulting mixture was stirred for 0.5 h at –78 °C, followed by addition of aldehyde 11 (0.27 g, 2.14 mmol). The reaction was maintained for 0.5 h at –78 °C and quenched with saturated NH4Cl solution (10 mL). The organic phase was separated, and the aqueous phase was extracted with EtOAc (3 × 10 mL). The combined organic phases were washed with saturated NaCl solution (100 mL), dried over anhydrous Na2SO4, and filtered. The filtrate was concentrated under reduced pressure to obtain a crude product. The crude product was purified by silica gel column chromatography (n-hexane/EtOAc, 9:1) to obtain 12a (0.28 g) and 12b (0.20 g) as a colorless oil (total 0.48 g, 84% yield, 12a/12b = 1.4:1, determined by 13C NMR).

- 28 The Experimental Procedures and Characterization Data for 1a,b In a 50 mL Schlenk tube, 10% palladium on carbon (0.10 g) was added at room temperature. The flask was charged with hydrogen, and 12a (82.3 mg, 0.31 mmol) in anhydrous ethanol (15 mL) and acetic acid (3 drops) were then added. The reaction mixture was stirred for 8 h under a hydrogen balloon. The catalyst was removed by filtering through a silica gel pad, and the filter was rinsed with n-hexane (30 mL). The combined filtrate and rinse were concentrated under a reduced pressure to obtain crude product. The crude product was purified by silica gel chromatography (n-hexane) to obtain 1a (77.7 mg, 93% yield) as a colorless oil.
