Abstract
The title compounds 5 was prepared by a stereoselective photocycloaddition of silyl enol ether 9 and benzaldehyde. In Lewis- and Brönsted-acid promoted ring opening reactions the oxetane is selectively cleaved to yield a 1,2-diol 6 which cyclizes under the reaction conditions to the dihydrofuran 11. The constitution of the final product was elucidated by reductive to the alcohol 14.
