实验步骤: To 2-indanol (Aldrich) (105 g, 0.78 mol) in pyridine (16 mL, 0.2 mol) and 340 mL of chloroform at -15° C. was added PBr3 (84 mL, 0.89 mol) over 45 min. The reaction mixture was stirred overnight at room temperature and extracted by addition of 450 mL of chloroform and 500 g of ice. The organic layer was washed twice with water, and dried over Na2SO4. The solvent was evaporated in vacuo, leaving a brown semi-solid. The product was distilled rapidly in vacuo and then fractionated to give 69 g (45%) 2-bromoindane, bp 90°-93°/3 mmHg; nD23 =1.5837. extracted by addition of 450 mL of chloroform and 500 g of ice The organic layer was washed twice with water dried over Na2SO4 The solvent was evaporated in vacuo leaving a brown semi-solid The product was distilled rapidly in vacuo

实验步骤: Sodium ethoxide (40 gms) was stirred in 1 L of dimethyl sulfoxide until solution was complete. Then, 100 g of ethyl acetamido-cyanoacetate was added, and again stirred until solution was complete. 2-Bromoindane (101 g) was slowly added, using a few ml of DMSO to wash the container and addition funnel. The solution was stirred over a weekend. to wash the container and addition funnel The solution was stirred over a weekend
