The synthesis of previously undescribed 22- and 23-deoxyanalogues of homocastasterone has been carried out, which makes it possible to obtain target compounds without replacing the carbon skeleton of the side chain. The key reactions in their synthesis were epoxy ring opening and radical debromination.Осуществлен синтез ранее неописанных 22- и 23-дезоксианалогов гомокастастерона, позволяющий получить целевые соединения без замены углеродного скелета боковой цепи. Ключевыми реакциями в их синтезе стали раскрытие эпоксидного цикла и радикальное дебромирование
