Abstract
alpha-oxothiophthalimides 2 can be oxidised the corresponding sulfinim ides 3 with m-chloroperoxybenzoic acid. Derivatives 3 in the presence of catalytic amount of pyridine generate the alpha-oxosulfines 4 which can be trapped by diene 5 to give dihydrothiopyranes 6 as mixture of diastereoisomers. The method appears simple and general since alkyl, a ryl and hetroaryl substituted thiopthtalimides can be fruitfully used.
