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.

Synthesis of Aryltetralin and Dibenzylbutyrolactone Lignans: (+/-)-Lintetralin, (+/-)-Phyltetralin, and (+/-)-Kusunokinin

Application of a general synthetic pathway for aryltetralin and dibenzylbutyrolactone lignans, starting from the lithium enolate of 3-(3,4-dimethoxybenzyl)butyrolactone (1) led to syntheses of (+/-)-lintetralin (4), (+/-)-phyltetralin (5), (+/-)-isogalcat

STRUCTURE AND SYNTHESYS OF HYPOPHYLLANTHIN, NIRTETRALIN, PHYLTETRALIN AND LINTETRALIN

Structures propounded for the four aryltetralin lignan constituents isolated from Phyllanthus niruri Linn. are confirmed by syntheses of their (+/-)-forms.
