摘要
The [3,2] sigmatropic rearrangement of sulphonium ylides derived from allyl sulphides with 1,2-related chiral centres was carried out with excellent stereochemical control. 1,4-Related chiral centres across an E double bond are set up stereospecifically by this reaction and good 4,5 diastereoselectivity is observed.
