Ahstracu The title anupormd 5 was prepared by a stenxsekuive photocyc1oiuJdiIioa of sibyl en01 ether 9 and beaualckhyde. In Lewis-and Br6nsted-ti promoted ring opening nxwions the oxehne is selectively cleaved to yield a 1,2diol6 which cyclizes III&S the rcacdon conditions to the dihydrufurau 11. The constih~tion of Ihe tinal pmduct was elucidated by nxiuctive dqpdahm to the alcohol 14.
