The stereoselective synthesis of tetrahydrofurans has been achieved from bromoalkynes and bromoalkenes by intramolecular radical cyclisation using a hypophosphite salt. This radical cyclisation strategy has successfully been applied to the total synthesis of a naturally occurring bioactive furanolignan, dihydrosesamin.
四氢呋喃的立体选择性合成已通过使用次磷酸盐的分子内自由基环化反应从溴代炔烃和溴代烯烃实现。这种自由基环化策略已成功地应用于天然存在的生物活性呋喃木质素二氢芝麻素的全合成。
