Abstract

Total syntheses of naturally occurring bis(methylthio)silvatin and its three stereoisomers were achieved from 1,4-dimethyl-3-(p-hydroxy)benzyl-2,5-piperazinedione. The configurational structures of the four stereoisomers, thus obtained, were definitely determined by the comparisons of their mps, specific rotations and NMR spectra.
