✦ Synopsis
Abstract
The mass spectra of O‐ethyl‐O‐aryl‐phenylphosphonothioates are investigated and discussed. Besides direct classical fragmentation (α‐fissions), migration of both an aryl group and a double bond occurs between sulphur and oxygen prior to fragmentation, resulting in some unexpected m/e valvues. The most abundant ion was m/e 157, which could be reasonably explained in terms of loss of a phenoxy moiety followed by ethylene expulsion.

## Abstract __N__‐stearoylethanolamine (NAE18:0) was reacted with O‐alkyl O‐aryl chlorophosphate and a series of O‐alkyl O‐aryl O‐2‐(stearamido)ethyl phosphates were synthesized to explore their antifungal activity. Compared with parent NAE18:0, title compounds without substitution or with methyl s
Identification and quantification of the enantiomeric excess of O-phosphoserine ( Ser) residues from post-translational modified proteins is now possible by the application of a very reproducible and sensitive mass spectrometric method. This technique is based on the different mass-spectral fragment
