PUMMERER REACTION OF BIOTIN SULFOXIDES: AN ACCES TO NEW FUNCTIONALIZED BIOTIN DERIVATIVES.

Application of the Pummerer reaction to Biotin sulfoxides gives a good acces to the corresponding thiolactol and thiolactone, which are key-compounds for the synthesis of new functionalized Biotin derivatives.
