General description
Reacted with dioxaphosphorinanes and iron catalyst to generate rearranged phosphonium ylide products.
Application
Diisopropyl azodicarboxylate (DIAD) is a commonly used reagent in organic synthesis for the preparation of useful chemical intermediates. It is often used in the Mitsunobu and aza-Baylis-Hillman reaction. DIAD is also used as a selective deprotecting agent of N-benzyl groups.
Reactant for preparation of:
- Chromenes resembling classical cannabinoids
- MK-3281 inhibitor of the hepatitis C virus NS5B polymerase
- Norbornene-based guanidine-rich polymers as mimcs of cell-penetrating peptides (CPP)
- Analogues of the Pseudomonas aeruginosa quorum-sensing molecule N-(3-Oxododecanoyl)-l-homoserine lactone with immunosuppressive but non-LasR-inducing properties
- Acceptor-donor-acceptor organic dyes for dye-sensitized solar cells
- 1,3-dioxane-2-carboxylic acid derivatives as PPARα/γ dual agonists
- Hydrazinophosphonates and hydrazinobisphosphonates via Mitsunobu and Arbuzov-type multicomponent application of the Morrison-Brunn-Huisgen betaine

Allylic phosphonium ylides are readily generated by the combination of an allylic alcohol, a carbene, and a chlorophosphite. Here we demonstrate that these intermediates undergo a thermal [3,3]-rearrangement to provide single isomers of homoallylic phosphonates in good to excellent yields.

A general approach to access sulfamate esters through preparation of sulfamic acid salts, subsequent activation with triphenylphosphine ditriflate, and nucleophilic trapping is disclosed. The method proceeds in modest to excellent yields to incorporate nucleophiles derived from aliphatic alcohols and phenols.
