SOLVOLYTIC HYDROPEROXIDE REARRANGEMENTS V. A Stereoselective Synthesis of trans-Fused Butyrolactones.

Stereoselective rearrangement of cis-5-(4-methoxybenzyl)-spirooctan-4-ol cis-1 in acidified THF-90percent H2O2 affords 9-oxabicyclononyl hydroperoxydes 7 and 8 which are converted to medium-ring, keto-butyrolactones 2 and 3.
