Dual Nickel/Photoredox-Catalyzed Deaminative Cross-Coupling of Sterically Hindered Primary Amines
Dorsheimer, Julia R.,Ashley, Melissa A.,Rovis, Tomislav
, p. 19294 - 19299 (2021/11/23)
We report a method to activate α-3° amines for deaminative arylation via condensation with an electron-rich aldehyde and merge this reactivity with nickel metallaphotoredox to generate benzylic quaternary centers, a common motif in pharmaceuticals and natural products. The reaction is accelerated by added ammonium salts. Evidence is provided in support of two roles for the additive: inhibition of nickel black formation and acceleration of the overall reaction rate. We demonstrate a robust scope of amine and haloarene coupling partners and show an expedited synthesis of ALK2 inhibitors.
Conformational Dependence of 13C SCS in 1-Methyl-1-phenylcyclohexanes
Cook, Michael J.,Nasri, Khalida A.
, p. 644 - 647 (2007/10/02)
13C chemical shift data are reported for a series of para-substituted 1-methyl-1-phenylcyclohexanes at 22 and -100 deg C.The magnitudes of the SCS at alkyl and cycloalkyl carbon positions are discussed.The SCS at C-methyl and C-4 are significantly differe
