from conjugate addition to the unsaturated thiol esters were determined by NMR spectroscopy. In the case of the alpha,beta,gamma,delta-unsaturated (sorboyl) thiol ester, both the 1,4-addition product and the beta,gamma-unsaturated-1,6-addition product formed, followed by diadduct. An in vivo test of the fluorescent alpha,beta-unsaturated thiol ester showed that this compound persisted on skin for 3 weeks
