The ‘diimino thioanhydrides’ of cyclohex-l-ene-1,2-dicarboxylic acid have been synthesized in a very simple manner by allowing 2-(arylaminothiocarbonyl)cyclohexanones 1 and isocyanides 3 to react in an acidic medium. A mechanism for this three-component reaction, based on isocyanide chemistry, is proposed.

Synthesis of pyridine derivatives by reactions of ?,?-unsaturated nitriles with 2-oxo-cycloalkano carbothioic acid anilides
The tandem Michael addition-cyclization of 2-oxo-cycloalkane carbothioic acid anilides 1-3 to benzylidenemalononitrile 4 yielded spiroannulated pyridines 5-7. Reaction of acrylonitrile with 2 and 3 gave 2,2-disubstituted Michael adducts 14, 15, whereas with 1 led to 2,2,5-tri(2-cyanoethyl)-cyclopentanone 11.
