Efforts toward the total synthesis of (±)-toxicodenane A utilizing an oxidopyrylium-based [5+2] cycloaddition of a silicon-tethered BOC-pyranone
Grabowski, Jacob P.,Ferrence, Gregory M.,Mitchell, T. Andrew
, (2020)
Synthetic efforts toward the tricyclic core of (±)-toxicodenane A are reported. This strategy takes advantage of the Feist-Benary furan annulation, Achmatowicz oxidative rearrangement, and oxidopyrylium-based [5+2] cycloaddition to access a key tetracycli

Pirrung, Michael C.,Lee, Yong Rok
, p. 6231 - 6234 (2007/10/02)
A new method for dipolar cycloaddition of diazocyclohexane-1,3-diones, leading to benzofuran derivatives, has been applied to the total synthesis of natural products from Tephrosia and Pongamia.
Polycyclic Compounds, XVIII. Synthesis of Isomeric Tetralones by Group Transpositions in Partially Hydrogenated Naphthalenes
Tochtermann, Werner,Koehn, Heinke
, p. 3249 - 3261 (2007/10/02)
Four pairs of carbon atoms change their positions relative to C-1/C-2 of 1 in the transposition sequence 1 -> 4 -> 5 -> 3 starting with the oxanorbornadienes 1.This can be used for 1,2- and 1,4-transpositions as shown in a variety of examples.During the conversion of 1b to 3f three groups move into other positions.
