A New Rearrangement: Conversion of a Diepoxycyclohexane into a Dihydropyrancarbaldehyde

Treatment of 2,7,7-trimethyl-3,8-dioxotricyclo2,4>octane 5 and derivatives with BF3 gave the corresponding 4,4,5-trimethyl-3,4-dihydro-2H-pyran-2-carbaldehyde 7 and traces only of 3,5,5-trimethyl-7-oxabicycloheptan-2-one 8.

SYNTHESYS AND STEREOCHEMISTRY OF 3,6-EPOXY-5-HYDROXY-5,6-DIHYDRO-β-IONOL, A NOVEL FLAVOR CONSTITUENT OF SUIFU TABACCO

(+/-)-3,6-Epoxy-5-hydroxy-5,6-dihydro-β-ionol was synthesized from β-ionone via 3,6-dihydroxy-α-ionone and its structure including the relative configurations was established as (+/-)-2β,5β-epoxy-2α--1β,3,3-trimethylcyclohexan-1α-ol by X-ray analysis.
