Descripción general

Reacted with dioxaphosphorinanes and iron catalyst to generate rearranged phosphonium ylide products.

Aplicación

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
