A FACILE SYNTHESIS OF THE SUBSTITUTED TETRAHYDRONAPHTHALENES BY THE BENZO-PETERSON REACTION

Thermal treatment of the o-hydroxymethylbenzylsilanes with an excess maleic anhydride or 2,3-dichloromaleic anhydride afforded the corresponding substituted tetrahydronaphthalenes stereoselectively in satisfactory yields presumably via the o-quinodimethane intermediates generated by the benzo-Peterson reaction.

The Synthesis of Lignans and Related Structures using Quinodimethanes and Isobenzofurans: Approaches to the Podophyllins

Novel routes to 1-aryl-5,6-dialkoxy-1,3-dihydrobenzothiophene 2,2-dioxides (13) and to the corresponding benzofuran (8) have been developed; these species yield quinodimethanes (12) via thermal extrusion of SO2 and isobenzofurans (5c) in an acid-cat

The Preparation of Lignans via Intermolecular Cycloadditions with Quinodimethanes

Certain lignans can be prepared using, as the key step, a thermal reaction between 1-(aryl)-1,3-dihydro-5,6-dialkoxy-benzothiophen 2,2-dioxides and dienophiles.
