実験手順

A solution of tert-butyl lithium in hexane (1.7M, 2 eq) is added dropwise to a solution of (S)-4-(2-iodoallyl)-2,2-dimethyl-1,3-dioxolane (1 eq) in diethyl ether at −78° C., and the reaction stirred at −78° C. for 30 min. Sulfuryl dichloride (1 eq) is added, the mixture warmed to room temperature and the solvents removed under reduced pressure.

後処理

  1. temperaturethe mixture warmed to room temperature
  2. customthe solvents removed under reduced pressure
