Synthetic process towards the bottom half portion of C20 oxygenated series of bryostatins is described. The stereogenic center at C20 position was constructed through a hydroxyl group-directed epoxidation by using mCPBA. It was found that silver (I) salt is an effective and mild reagent for regioselective ring cleavage of α-bromoepoxides into the corresponding α-hydroxyketones via oxonium ion intermediates
