threo-Diethyl 2-ethyl-2-hydroxy-3-(4-methylbenzenesulfonamido)succinate
The asymmetric unit of the title compound, C(17)H(25)NO(7)S, contains two independent mol-ecules, which are enanti-omers forming a hydrogen-bonded dimer associated with two R(2) (2)(7) patterns. In each mol-ecule, one ethyl group from the two available ethyl ester functional groups is disordered. In one mol-ecule, the ethyl group of the ester function from an α-carb-oxy-lic acid is positionally...
متن کاملReaction of diethyl pyrocarbonate with nucleic acid components. I. Adenine.
The use of diethyl pyrocarbonate as a nuclease inhibitor in the preparation of RNA of high molecular weight has prompted a study of the possible reactions of this compound with nucleic acid components under the conditions generally employed for providing inhibition. The first substrate investigated was adenine, which has been found to undergo ring opening with the formation of 5(4)-N-carbethoxy...
متن کاملThe reaction of rabbit muscle creatine kinase with diethyl pyrocarbonate.
The reaction of rabbit muscle creatine kinase with diethyl pyrocarbonate was studied. It was found that up to five of the sixteen histidine groups per enzyme subunit could be modified, and under the conditions employed, there was no evidence for formation of the disubstituted derivative of histidine. Evidence was obtained for small but significant amounts of modification of lysine and cysteine ...
متن کاملDiethyl (1-hydroxy-1-phenylethyl)phosphonate
The title compound, C(12)H(19)O(4)P, has a distorted tetra-hedral geometry around the P atom. The molecules form dimers with R(2) (2)(10) ring motifs due to inter-molecular O-H⋯O hydrogen bonds. The double-bonded O atom of the phospho-nate group behaves as an acceptor and the hydr-oxy group acts as a donor. Both of the ethyl groups are disordered with occupancies of 0.55:0.45 and 0.725:0.275.
متن کاملHyperconjugation in diethyl ether cation versus diethyl sulfide cation.
Ionization of a molecule can greatly alter its electronic structure as well as its geometric structure. In this collaborative experimental and theoretical study, we examined variance in hyperconjugation upon ionization of diethyl ether (DEE) and diethyl sulfide (DES). We obtained the experimental gas phase vibrational spectra of DEE, DES, DEE(+), DES(+), DEE(+)-Ar, and DES(+)-Ar in the wavenumb...
