Compounds of formula (I) wherein R1, R2,R3,R4,R5,R23,R24,L, A and Bare as defined in claim 1, or pharmaceutically acceptable salts thereof are disclosed. The compounds of formula (I) possess utility as cytochrome P450 monooxygenase 11A1(CYP11A1) inhibitors. The compounds are useful as medicaments in the treatment of steroidreceptor, particularly androgen receptor,dependent diseases and conditions, such asprostate cancer.
A simple, efficient, and odorless deborylthiolation of aryl- and alkenylborons with thiosulfonates has been achieved under mild conditions using a copper catalyst.

Treatment of nitroarenes having electron-withdrawinggroups at the ortho or para position with alkanethiol in the presence of cesium carbonate in dimethyl sulfoxide at 25 °C leads to nucleophilic displacement of the nitro group with the alkylthio group. Cesium carbonate is superior to other bases such as potassiumcarbonate, sodium carbonate, and triethylamine. The cesium-mediated nucleophilic aromatic

nitride material can be combined with homogeneous nickel catalysts for light-mediated cross-couplings of aryl bromides with alcohols under mild conditions. The metal-free heterogeneous semiconductor is fully recyclable and couples a broad range of electron-poor aryl bromides with primary and secondaryalcohols as well as water. The application for intramolecular reactions and the synthesis of active pharmaceutical
