(Chemical Equation Presented) The cycloaddition of 4-iodosydnones with terminal alkynes proceeds with excellent regiocontrol to provide 5-iodo pyrazoles. These products participate smoothly in subsequent C-C and C-heteroatom bond forming processes.

Methyl propiolate, tetrolate, and phenylpropiolate combine with diphenylnitrilimine (1) to afford regioisomeric cycloadducts; the preferential orientation shifts in the sequence given from the pyrazole-5-carboxylic ester to the 4-carboxylic ester.Correspo
