| Application: | 1-Ethylpiperidine hypophosphite (EPHP) may be used in the following studies: • As water-soluble chain carrier for the efficient radical cyclization in water for various hydrophobic substrates. • In the main radical-cyclisation step for the synthesis of the phytotoxic metabolite alboatrin and its epimer. • Preparation of bifunctional pentafluorophenyl/2,4,6-t • Chemoselective radical reduction of the iodine atom in 1-deoxy-1-halo-1-iodo-ald |
| Application: | Reagent for: Synthesis of spiroketals via intramolecular iodoetherification A facile radical cyclization diverted to a rearrangement-cyclization with base Radical deoxygenation Synthesis of allylic H-phosphinates |
| General description: | 1-Ethylpiperidine hypophosphite promotes the carbon-carbon bond forming radical reactions in both aqueous and organic media. EPHP plays an important role of a good chain carrier during the radical addition of gem-dihalocompounds to electron-deficient olefins. It has been reported as a suitable radical reducing agent for organic halides. |
