(+)-Dipentene Content Analysis

Gas-liquid chromatography analysis was performed using a polar column as in GT-10. Problems: The length of the stainless steel column is 300cm × 3cm; the column packaging base product is polyethylene glycol 20M, 10% weight, as well as the solid service provider is 10 to 20 mesh diatomaceous earth that has been treated with hot antacids, silicified and pickled; its ordinary free fall quantity Thickness 0.2 g/cm3, bit size 80 ~ 100 mesh; provider gas, helium circulation rate 30ml/min. Detector, thermal conductivity cell. Column temperature level, 100 ~ 225 ℃, 4 ℃/ min. Injection quantity, 0.2 μl. After that calculate the material based on the peak location.

Synthesis of (+)-Dipentene

图1 (+)-柠檬烯的合成路线[2]。

A service of 1 M SnCl4 in hexane (0.5 mL) was contributed to (R)-2-acryloyloxy-(1,1′-biphenyldicarboxylic acid)-2′-p-toluenesulfonate (0.5 mmol) In a mix of 1-chloropropane (2.5 mL). The remedy was distilled dropwise at -78 ° C. The response blend was mixed at -78 ° C for 4-12 hours. The reaction blend was relieved with saturated NaHCO3 remedy. The response combination was warmed to room temperature level. The resulting mixture was removed two times with pentane. The combined organic layers were dried out over magnesium sulfate. The consolidated natural layers were filtered. The combined natural layers were focused in vacuo. Chromatography of the crude product on silica gel (eluting with pentane) afforded the title substance (+)-limonene. The synthesis course is shown in Figure 1.

图2 (+)-柠檬烯的合成路线。

Tosyl chloride (190 mg) was included in (R)-2-formyloxy-2 ′-hydroxy-1,1 ′-binaphthyl (423 mg) and also triethylamine (420 mL) at -78 ° C., 3 mmol) in a stirred service in diethyl ether. The reaction combination was warmed to space temperature. The response blend was mixed for 5 hrs. Put the reaction mix into saturated NaHCO3 option. The response mix was extracted with diethyl ether. The reaction combination was dried out over MgSO4. The reaction combination was concentrated. The crude product was detoxified by silica gel column chromatography utilizing hexane-ethyl acetate (15:1) to offer the title substance (+)-limonene. The synthesis path is displayed in Figure 2.
