Each of the intermediates 10 and 12 were used in the following transformation without purification and were not fully characterized. All other compounds were isolated, purified, and exhibited spectra in accord with assigned structures and gave satifactory elemental analyses or molecular mass determinations

Note that the use of the acetal functionality in 13 was to both activate the diene and to provide the enol functionality in the cyclized product. Consequently, the ketal formed in 16 as a result of the Diels-Alder cyclization does not actually serve as a protective group
