This disclosure relates to modulators of liver receptor homologue 1 (LRH-1) and methods of managing disease and conditions related thereto. In certain embodiments, modulators are derivatives of hexahydropentalene. In certain embodiments, this disclosure relates to methods of treating or preventing cancer, diabetes, or cardiovascular disease by administering an effective amount of a hexahydropentalene derivative disclosed herein.

The present disclosure relates generally to the field of synthetic organic chemistry. More specifically, the disclosure is directed to a continuous flow process for synthesis of azides from alcohols and peroxides, wherein the process comprises azidation with trimethylsilyl azide and a catalyst Amberlyst-15. It is a non-hazardous, mild and controlled reaction giving good yields of azides. The azides can be further employed for synthesis of medicinally and industrially useful chemicals.
