Article abstract of DOI:10.1016/0040-4039(91)80675-V

A practical modification of the Mitsunobu protocol for effecting stereochemical inversions of alcohols has been discovered in which use of p-nitrobenzoic acid as the nucleophilic partner results in significantly improved yields with relatively hindered su
