Abstract

9b-e, 14 and 9f15 were prepared by the reported methods. Ozonolysis of a Vinyl Ether 1 in the Presence of an a,@-Unsaturated Aldehyde 4. The reaction of a vinyl ether (200 mg) was run in CH2C1,(20 mL) or in ether (20 mL) in the presence of an a, fl-unsaturated aldehyde (5 mol equiv). After evaporation of the solvent in vacuo, the products were separated by column chromatography on silica gel (elution with benzene/hexane (23 to 3: 2)). trans-3-P henyl-5 ...
