| Abstract: | An ?,δ-unsaturated alcohol tethered with a hydroxyl group, that is, (E)-2-styrylbutane-1,4-diol (1) undergoes a smooth bicyclization with various aldehydes in the presence of 10 mol % InBr3 and at 0 °C to afford a novel series of hexahydro-1H-furo3,4-c]pyran derivatives in good yields with high diastereoselectivity. |
