A number of C ‐glycosylindazoles were prepared by 1,3‐dipolar cycloaddilion of several α‐diazoketoses to benzyne. When the cycloaddition reaction was carried out with benzyne derivatives the two possible isomeric indazoles were obtained in most of the cases. Structural assignments were made on the basis of nmr data.
