Electron impact induced fragmentation of the title compounds obeys a route where the lactam moiety, OCNH, is cleaved first, with the accompanying formation of a cycloalkene ion.This can be verified by low-resolution, high-resolution, B/E and B2/E spectra as well as by collisional activation spectra of, for example, the ions m/z 82 and 67 from 7-azaabicyclooctan-8-one and from cyclohexene.The only, and fairly weak, fragment ions including O and N are +, kH2k-2N>+ (k=5-8) and +.The ammonia chemical ionization spectra are also characteristic for all four lactams and show the same dominant ions in all cases, namely +, +. and +..

Substrates that selectively encourage the growth of specific cell types are valuable for the engineering of complex tissues. Some cell-selective peptides have been identified from extracellular matrix proteins; these peptides have proven useful for biomat

The invention of new strategies for the design of protein-mimetic oligomers that manifest the folding encoded in natural amino acid sequences is a significant challenge. In contrast to the α-helix, mimicry of protein β-sheets is less understood. We report
