摘要：

The preparation of hitherto unknown steroidal heterocycles containing pyrazole moiety fused to 6,7-position of the steroidal nucleus is described. These heterocycles have been prepared by the action of Vilsmeier reagent with steroidal tosylhydrazone in DMF. The structures of the compounds have been established on the basis of their elemental analysis and spectral data. A general mechanistic scheme for these reactions is also suggested based on current and previous results.
