✦ Synopsis
Butyl-7-hydroxyperhydrofuro[2,3-blfuran was synthesized via a furan-alcohol which was derived by a coupling reaction with an epoxide and a new reagent, Li di(3-furyllcuprate. The configuration of the t-butyl substituent and the conformation of the furo[2,3-blfuran ring were decided by the combination of the LIS experiment and the empirical force-field calculation.
