A stereoselective route to trans-2,5-disubstituted tetrahydrofurans
Kang,Hwang,Kim,Lim
, p. 5917 - 5920 (2007/10/02)
An efficient stereocontrolled route to trans-2,5-disubstituted tetrahydrofurans from trans-4-phenyl-3-buten-1-ol derivatives has been developed by using phenylselenyl chloride with zinc bromide in DME at -55°C.
