The cyclopropenone catalyzed nucleophilic substitution of alcohols by methanesulfonate ion with inversion of configuration provides an alternative to the Mitsunobu reaction. The new reaction avoids the use of azodicarboxylates and generation of hydrazine and phosphine oxide byproducts and is compatible with a range of functionality.
