The Use of Diethyl Azodicarboxylate and Triphenylphosphine in Synthesis and Transformation of Natural Products
TL;DR: In this article, a reagent formed by combining diethyl azodicarboxylate (DEAD) and triphenylphosphine (TPP) could be utilized in the intermolecular dehydration between an alcohol and various acidic components such as carboxylic acids, phosphoric diesters, imides, and active methylene compounds.
Journal ArticleDOI
Conformational analysis—CI
TL;DR: In this paper, it was concluded that the gauche-butane interaction has been incorrectly interpreted as to origin, and that the relationship between methyl groups is not the cause of the relative instability of gauche conformations.

Efficacious modification of the mitsunobu reaction for inversions of sterically hindered secondary alcohols
TL;DR: In this article, a 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 substrates.
Journal ArticleDOI
Direct conversion of activated alcohols to azides using diphenyl phosphorazidate. A practical alternative to mitsunobu conditions
TL;DR: In this article, 14 alcohols were converted to their corresponding azides with inversion of configuration using diphenyl phosphorazidate and DBU, and the resulting azides were converted into azides.
