Transition metal-free intermolecular a-C-H amination of ethers at room temperature

We describe a new method for the intermolecular amination of the α-C-H bonds of ethers. A hypervalent iodine reagent was used as oxidant to enable the amination of cyclic and acyclic alkyl ethers with a wide range of amides, imides, and amines. The amination occurred at room temperature and without a transition metal catalyst. The method could be used to synthesize the anti-cancer prodrug Tegafur and its analogues.
Deuterium exchange as an indicator of hydrogen bond donors and acceptors
Steffel, Lauren R.,Cashman, Timothy J.,Reutershan, Michael H.,Linton, Brian R.

Hydrogen-deuterium exchange has been used to determine the hydrogen bonding preferences of a select group of small peptides in organic solvents. This kinetic analysis permitted comparison of hydrogen bond strengths in relation to controls and also indicated the identity of both hydrogen bond donors and hydrogen bond acceptors. Copyright
Phosphorus in organic synthesis. Acyloxyphosphonium salts as chemoselective acylating reagents
Froyen, Paul
, p. 5359 - 5362 (2007/10/03)
Acyloxytriphenylphosphonium salts 1 prepared in situ react with a variety of aminophenols to give the corresponding amides in excellent yields. At -25°N-acylated products are formed exclusively, whereas 0°some O-acylated products are observed. 1 is also a
