A novel synthetic route is reported for the preparation of steroidaltriazoles via intramolecular 1,3-dipolar cycloaddition of a steroidal 16,17-seco-17-diazo-16-nitrile system. The structures of the products are established by X-ray and NMR studies. The in vitro antiproliferative activity of the steroidaltriazoles against three tumor cell lines was evaluated.
