The thiol group of cysteine adds to the double bond of unsaturated lactones and relatedcompounds to give thio amino-acids. In certain cases, cyclisation and dehydration leads to the formation of stable, unsaturated, 8-membered cyclic lactams.

proton-decoupled 13C-nuclearmagneticresonance spectra have been determined and in almost all cases, each carbon resonance has been unambiguously assigned by a combination of off-resonance and specific decoupling techniques. The effect of solvent and pH on chemical shifts is discussed. The objective of these studies is to provide models relevant to the use of 13C-labelled electrophilic inhibitors as probes of enzyme
