| 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. |
| Application: | 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-hom • Acceptor-donor-acceptor organic dyes for dye-sensitized solar cells • 1,3-dioxane-2-carboxyli • Hydrazinophosphonates and hydrazinobisphosphonates via Mitsunobu and Arbuzov-type multicomponent application of the Morrison-Brunn-Huisgen betaine |
