A convenient one-pot procedure for the preparation of pyrazoles by 1,3-dipolar cycloaddition of diazo compounds generated in situ has been developed. Diazo compounds derived from aldehydes were reacted with terminal alkynes to furnish regioselectively 3,5-disubstituted pyrazoles. Furthermore, the reaction of

New Aromatic Terminal Alkynes

The terminal alkyne functionality has a wide range of applications including most recently the synthesis of spiropyran substituted 2,3-dicyanopyrazines and (±)-asteriscanolide, as well as conversion to enamines using resin-bound 2° amines.
