Synthesis of α-methylene-β-hydroperoxy sulfoxides by regioselective photooxygenation (Schenck Reaction) of racemic vinyl sulfoxides

Adam,Kumar,Saha-Moller

, p. 1525 - 1528 (1995)

The β-hydroperoxy vinyl sulfoxides 3 were synthesized in good to excellent yields by regioselective photooxygenation of racemic vinyl sulfoxides 2. Moderate diastereoselectivities were observed in the ene reaction of singlet oxygen (Schenck Reaction) with
