摘要
A convenient preparation of 2,3-dibromo-1-(phenylsulfonyl)-1-propene (DBP, 1) is available through the one-pot propargylation and oxidation of thiophenol to give the propargyl sulfone 11, which is isomerized and brominated in another one-pot reaction. The new preparation is significantly more scalable, as well as more convenient and robust than the prior art.
