Rm. Lawrence, SYNTHESIS OF PENTAFLUOROPHENYLTHIOHYDANTOIN DERIVATIVES OF ADDUCTS FORMED WITH DL-VALINE BY ACRYLONITRILE AND CYANOETHYLENE OXIDE, Tetrahedron letters, 35(22), 1994, pp. 3767-3770
Pentafluorophenylthiohydantoin (PFPTH) derivatives of adducts formed w
ith dl-valine by both acrylonitrile and its putative metabolite, cyano
ethylene oxide have been syntbesised, the latter via conjugate additio
n of dl-valine to phenyl vinyl sulfoxide and subsequent Pummerer rearr
angement and hydrolysis.
