In the present study, a general approach for the synthesis of 1-(1-indol-3-yl)-3,3-dimercaptoprop-2-en-1-one and 5-(1-indol-3-yl)-3-1,2-dithiole-3-thione was performed. They are currently used as efficient precursors for the synthesis of some new compounds bearing five- and/or six-membered heterocyclic moieties, e.g.

Background: A series of new pyrimidines and thiazoles containing camphor moiety were synthesized under both conventional and microwave irradiation techniques.

Methods: The condensation of camphor either with aminoguanidine or thiosemicarbazide gives the camphor hydrazine carboximidiamide 2 and the camphor thiosemicarbazone 3, respectively. Refluxing of 3 with chloroacetonitrile afforded the camphor thiazol-4-imine 4.
