The benzoyl group participation in the epoxide ring opening reaction of 26-benzoxy-24,25-epoxycholesterol derivatives on treatment with perchloric acid in tetrahydrofuran was clearly demonstrated by the transformation of (carbonyl-(18)O)-3β,26-dibenzoxy-24,25-epoxycholest-5-ene into (25-(18)O)-24,25,26-trihydroxycholesterol derivatives.Keywords - epoxide ring opening reaction; benzoyl group participation; 26-benzoxy-24,25-epoxycholesterol; carbonyl-(18)O-label; mass spectrometry of (18)O-sterol
