C-6α and C-7α androstanes were studied to disclose which position among them is more convenient to functionalize to reach superior aromatase inhibition. In the first series, the study of C-6 versus C-7 methyl derivatives led to the very active compound 9 with IC50 of 0.06 μM and Ki = 0.025 μM (competitive inhibition). In the second series, the study of C-6 versus C-7 allyl derivatives led to the best
