  Synthesis of 1-diethoxyphosphoryl-1-methylthio-thioacetamides and 1-methylthioethenethioamides. An unusual intramolecular α-desulfenylation of thioacetamides

  摘要：

  Addition of the lithiated alpha-phosphoryl sulfide 1-Li to alkyl or aryl isothiocyanates 4(a-f) and phenyl isocyanate 4g was found to afford 1-diethoxyphosphoryl-1-methylthio-thioacetamides 5(a-f) and -acetamide 5g, respectively. In the case of the reaction with the p-chlorophenyl isothiocyanate 4e, the alpha-desulfenylated product 6 was isolated and on the basis of P-31-NMR experiments a mechanism of its formation was proposed. The phosphonates 5(a-f), which exist in the thione form, were found to undergo the Homer-Wittig reaction with aromatic aldehydes affording 1-methylthioethenethioamides 14(a-f).
