## Abstract The conformations of [Arg^8^]vasopressin (AVP) analogues substituted at positions 2 and 3 with N‐methylphenylalanine (MePhe) enantiomers were earlier investigated by using nuclear magnetic resonance (NMR) spectroscopy in aqueous solution. A comparison of the results obtained in H~2~O/D~

## Abstract Photoionisation mass spectra of __N__‐methylamides of __N__‐acetyl derivatives of the following amino acids have been studied: alanine, valine, leucine, serine, threonine, phenylalanine, tyrosine, tryptophan and proline. The study also included methyl esters of __N__‐acetyl tyrosine, __
## Abstract Various kinds of NCA's were polymerized in dimethyl sulfoxide (DMSO). DL‐Alanine NCA polymerized at a fast rate without initiator, the rate being represented by __R__~__p__1~ = __k__[M]^1/2^. When the polymerization was carried out in chloroform in the presence of DMSO, the rate was rep
Electropolymerization of N,N-dimethylacrylamide has been performed in aqueous sulfuric acid solution, using unsized AS-4 graphite fibers as the working electrode. The electropolymerized poly( N,N-dimethylacrylamide) deposited on the surface of the graphite fiber working electrode. The formation of p
The 'H-nmr studies were extensively carried out to elucidate preferred conformations of dipeptides CH,C\*O-X-NHCH,, with X = Abu, oval, and Val in various solvents. The vicinal 'H--'H coupling constants for the NH-CnH moiety and those around the C"-Cp bond in the articulated side chain provided the
## Abstract **Summary:** Carboxylic acids were efficiently activated with __N__,__N′__‐carbonyldiimidazole (CDI) and applied for the acylation of cellulose under homogeneous conditions using dimethyl sulfoxide (DMSO)/tetrabutylammonium fluoride trihydrate (TBAF) as solvent. The simple and elegant m
