Synthesis of dithioesters

Selective addition reactions of various monothiocarboxylic acids to the
ynamide MYTsA furnish α-thioacyloxyenamides. A subsequent transesterification
with alcohols or thiols affords thionoesters and dithioesters, respectively. The
method offers broad substrate scope, mild reaction conditions, and good yields.

The reaction of carboxylic acids with various thiols or alcohols in the
presence of phosphorus pentasulfide proceeded effectively to afford the
corresponding dithiocarboxylic esters in high yields.
