Significance
The construction of C-C bonds through sigmatropic rearrangements can be a useful and a non-obvious strategy in synthesis. In this work, the authors explore the acid-catalyzed Stevens [3,3]-sigmatropic rearrangement. The described transformation proceeds with moderate to good yields. A variety of E-alkenes are generated in diastereoselectivity of up to 20:1.
