A series of unnatural amino acids functionalized with sterically shielded pyrroline nitroxides were synthesized. Their reduction by ascorbate/glutathione indicates that L-cysteine functionalized with gem-diethylpyrroline nitroxide is reduced at the slowest rate and is comparable to that measured for the most resistant to reduction pyrroline and pyrrolidine… (More)
Reaction of 1,2,2,6,6-penatamethyl-piperidine-4-one (A) with ketone (B) and NH 4 Cl in DMSO at 55 O C for 5 hrs (RXN 1). Multiple trials using different equivalents of ketones and NH 4 Cl, temperatures, and dilutions were attempted.
In the structure of the title complex salt, (Et2NH2)2[CuCl4], the asymmetric unit consists of four unique di-ethyl-ammonium cations and three unique tetra-chlorido-cuprate anions. Two of the three anions are located with their copper atoms on independent crystallographic twofold axes, while the remaining tetra-chlorido-cuprate is located at a general… (More)
