反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 3-methylene bicyclo[3,2,1]octan-8-one (0.14 g, 1.04 mmol, 1.0 eq.) in benzene (10 mL) was added ethylene glycol (0.65 g, 16 eq.) and PTSA (0.01 g, 0.06 eq.). The reaction was equipped with a Dean-Stark and heated at reflux overnight. After cooling to room temperature, Et3N (0.15 mL) was introduced and the resulting mixture was passed through a cake of SiO2 and MgSO4. The cake was washed with CH2Cl2 and the combined filtrates were concentrated to give 3-methylene bicyclo[3,2,1]octan-8-one ethylene ketal (0.21 g, >100%). The reaction was equipped with a Dean-Stark heated at reflux overnight The cake was washed with CH2Cl2 the combined filtrates were concentrated
