Dipolar cycloaddition reaction of diazoalkanes with trimethylsilyl substituted alkynes. Steric control of regiochemistry by the trimethylsilyl group

A study of the cycloaddition behavior of several trimethylsilyl substituted alkynes with 2-diazopropane and diazomethane has been carried out. Aryl or alkyl ethynyl sulfones react to give 5-sulfonyl substituted 3H-pyrazoles which extrude nitrogen on photo
