  Application of microwave technique allowed to accomplish novel, general and “greener” one‐pot protocol for the synthesis of isothiocyanates from amines. Reactions are easily scalable and take place without racemization of chiral amines. Decomposition of the intermediate dithiocarbamates into isothiocyanates proceeds without any additional desulfurating agent under these conditions.

  indoline-(thio)urea were designed and prepared using indoline(s) as a new platform and tested as organocatalysts in the Michael and Morita–Baylis–Hillman reactions. Most of the compounds were found to be very active catalysts although they did not promote the enantioselectivity. As agents for the conversion of thiocarbonyl compounds into carbonyl compounds, potentials of PIFA and DDQ were also displayed
