Hydropyridylation of Olefins by Intramolecular Minisci Reaction
Bordi, Samuele,Starr, Jeremy T.
, p. 2290 - 2293 (2017/05/12)
An unprecedented cheap, mild and easy methodology for an intramolecular Minisci reaction based on a hydrogen atom transfer (HAT) initiated hydrofunctionalization of olefins was developed. The method is suitable for the construction of unusual dihydropyrano-pyridine and 1,2,3,4-tetrahydronaphthiridine structures and, unlike most similar reactions, does not require exclusion of air from the reaction medium.
A mild catalytic system for radical conjugate addition of nitrogen heterocycles
Aycock,Wang,Jui
, p. 3121 - 3125 (2017/04/04)
The direct addition of pyridine and diazine units to electron-poor alkenes has been achieved via a redox radical mechanism that is enabled by limiting the effective concentration of the hydrogen-atom source. The described method is tolerant of acidic functional groups and is generally applicable to the union of a wide range of Michael acceptors and 6-membered heterocyclic halides.
Diastereoselective intramolecular SmI2-H2O-amine mediated couplings
Dahlen, Anders,Petersson, Annika,Hilmersson, Goeran
, p. 2423 - 2426 (2007/10/03)
The effectiveness of SmI2-H2O-amine mixture for intramolecular couplings was discussed. Diastereoselectivities in the coupling of O-cyclohexanyliodophenol derivatives were provided into heterocycles. The amount of coupled product improved significantly as SmI2, the substrate and amine were premixed followed by a gradual addition of water.
THE REACTIONS OF ALLYL o-BROMOARYL ETHERS, N-ALLYL o-BROMOACETANILIDE, AND RELATED COMPOUNDS WITH TRIBUTYLTIN HYDRIDE IN THE PRESENCE OF ACTIVATED OLEFINS
Togo, Hideo,Kikuchi, Osamu
, p. 373 - 381 (2007/10/02)
o-Bromophenyl allyl ether, N-allyl o-bromoacetanilide, and related compounds reacted with tributyltin hydride in the presence of activated olefins to give 2,3-dihydrobenzofuran, 2,3-dihydroindole, and analogous derivatives in modest yields respectively vi
