A known one-pot procedure for the synthesis of 2-(phenylselanyl)tetrahydrofurans could be applied to the transformation of γ-lactones 3a-c into 2-(phenylselanyl)tetrahydrofurans 1a-c. Surprisingly, formation of γ-hydroxydiselenoacetals 5b and 5c was observed when γ-lactols 4b and 4c were treated with selenophenol and boron trifluoride etherate.
已知制备2-(苯硒基)四氢呋喃的一锅法可以应用于将γ-内酯3a-c转化为2-(苯硒基)四氢呋喃1a-c。令人惊讶的是,当γ-醇内酯4b和4c与苯硒酚和三氟化硼乙醚合物处理时,观察到了γ-羟基二硒缩醛5b和5c的形成。
