Abstract

A convenient method for the synthesis of 3-methylthioindoles has been established which does not use smelly compounds such as thiol derivatives. The method, which introduces an alkyl-or arylthio-group into the C 3-position of the indole skeleton, was extended to the direct introduction of a methylthio or bromo group at the C 2-position using 3-methylthioindoles. No dimerization occurred, and the reaction mechanism was confirmed. The products have the ...
