CYCLOPENTANATION WITH β-METHYLTHIO-ALLYL PHENYL SULFONE
Barre, V.,Uguen, D.
, p. 6045 - 6048 (2007/10/02)
The allylic thiosulfones 2 resulting from the addition of thiols to propargylic sulfone 1 have been used to convert enones into diketo-sulfones which then led to bicyclo alkanediones by either tris-anionization then cupric oxidation or treatment with rhodium acetate of the corresponding diazoketo-sulfone.
